1. 046If margin goes down by 5 percent, how much would you need to increase revenue to balance it out?Unit economics and costingIntermediatetechnicalSycamore PartnersConsumer and Retail · New York · 2026

   Say this

   It depends entirely on whether the 5 points came off price or off cost, and I would say that before calculating. If the margin loss is a price cut, you need a very large volume increase, because the extra units only earn the reduced margin.

   Then walk it

   1. Set it up cleanly. Take 100 of revenue at a 20 percent contribution margin, so 20 of profit. Cut price by 5 percent: revenue per unit falls to 95, cost per unit stays at 80, so contribution per unit drops from 20 to 15.
   2. To rebuild 20 of profit at 15 per unit you need 1.33 units for every one you sold, so volume has to rise 33 percent. That is the number, and it is why discounting is so dangerous in a low-margin business.
   3. The general formula: required volume increase equals old contribution margin divided by new contribution margin, minus one. At a 40 percent margin, the same 5-point price cut only needs about a 14 percent volume lift. Low-margin businesses cannot discount their way anywhere.
   4. If instead margin fell 5 points because of input cost inflation, the arithmetic on volume is similar but the answer is different: volume does not fix a cost problem profitably, price or procurement does.
   5. And if 'margin down 5 percent' means relative, from 20 percent to 19, the answer is roughly a 5.3 percent revenue increase. I would ask which the interviewer means rather than guess, because the two readings differ by a factor of six.
   6. Then the real-world caveat: 33 percent more volume usually needs more capacity, more working capital and more service cost, so the true breakeven volume is higher than the arithmetic. Discounting almost never pays for itself.

   Where candidates lose it

   Assuming 'margin down 5 percent' means percentage points and not saying so, or answering 5 percent more revenue because you treated margin as a constant percentage. Clarify the base, then use the contribution ratio, not the gross margin percentage.

   Expect next

   • Now do it at a 40 percent margin.
   • What if the cost base is mostly fixed?
   • Would you ever recommend the price cut anyway?

2. 087If a date is a Monday, what day of the week will the same date be a year from now?Brainteasers and estimationIntermediatetechnicalOaktree Capital ManagementGeneralist · Los Angeles · 2022

   Say this

   Tuesday, unless a 29 February falls in between, in which case Wednesday. A normal year is 365 days, which is 52 weeks plus one day, so the day of the week advances by one. A leap year adds two.

   Then walk it

   1. The mechanism: 365 divided by 7 is 52 remainder 1. The remainder is the whole answer, so a year later is one weekday forward.
   2. 366 divided by 7 leaves remainder 2, so across a leap day you advance two, landing on Wednesday.
   3. The condition to state, because it is the actual test: does 29 February fall inside the twelve months between the two dates? So a date in March 2023 to March 2024 crosses the leap day and advances two; a date in March 2024 to March 2025 does not and advances one.
   4. The same modular arithmetic answers the harder version. Ten years forward is ten plus the number of leap days, modulo seven. Ten years with two leap days is 12 mod 7 equals 5, so five weekdays forward.
   5. Say the assumption out loud, that you are on the Gregorian calendar and ignoring the century rule where 1900 was not a leap year but 2000 was. That earns credit because it shows you checked the edge case rather than got lucky.
   6. And the reason these get asked in a credit or corporate finance interview: they are testing whether you reach for the structure, remainder after dividing by seven, rather than counting.

   Where candidates lose it

   Answering Tuesday with no condition attached. The interviewer is waiting to see whether you raise the leap year yourself. Saying 'Tuesday, or Wednesday if a 29 February falls in between' answers it completely in one sentence.

   Expect next

   • What about ten years from now?
   • What day of the week were you born on?
   • How many leap days between 2000 and 2100?

3. 088Quick mental arithmetic: a business does 4.2 crore of revenue a month at a 23 percent EBITDA margin. What is annual EBITDA, and what is the business worth at 9 times?Brainteasers and estimationIntermediatetechnicalMSMorgan StanleyUtilities · Baltimore · 2025

   Say this

   Annual revenue is about 50 crore, EBITDA is about 11.6 crore, and at 9 times that is roughly 104 crore of enterprise value. Round as you go and say the rounding out loud.

   Then walk it

   1. Revenue: 4.2 times 12 is 50.4 crore. Call it 50 and note you rounded down slightly.
   2. EBITDA: 23 percent of 50 is easiest as 25 percent minus 2 percent. A quarter of 50 is 12.5, 2 percent of 50 is 1, so 11.5. The precise figure on 50.4 is 11.6.
   3. Value: 9 times 11.6. Do 10 times minus 1 times, so 116 minus 11.6, about 104 crore. Never multiply by 9 directly in your head.
   4. The techniques worth having automatic: break percentages into round components, multiply by 10 and subtract, use the rule of 72 for doubling times, and remember that a 10 percent margin means enterprise value equals 0.9 times revenue at a 9 times multiple.
   5. Then add the detail that gets you the point: say whether this is enterprise or equity value. At 104 crore of enterprise value with 30 crore of net debt, the equity is 74. Interviewers ask the mental maths question and then check whether you know what the number is.
   6. And narrate. An interviewer cannot mark a silent pause, but they can mark a clean decomposition even if you fumble the last digit.

   Where candidates lose it

   Going silent and trying to be exact. Speed with narration beats precision in silence. Also, quoting the 9 times number as equity value. State that it is enterprise value and that you would deduct net debt.

   Expect next

   • Now tell me the equity value if net debt is 30 crore.
   • If EBITDA grows 15 percent a year, how long until it doubles?
   • What multiple would make this worth 150 crore?
