This can be done using successive percentage formula (a + b + ab/100)% is the final percentage change.

Here A = 10 and B = -10

So final value would be (10 - 10 -100/100) = -1%

Which means 1% less.

So option C.

pushpitkc · Answer

Using numbers, let revenue be 100.

In April after increase of 10%, the revenue becomes 110. As there is a subsequent decrease in May, the revenue is reduced by 11 and becomes 99, 1 less than revenue originally.

This is 1% less than the original revenue(Option C)

Abhishek009 · Answer

There is a shortcut formula for solving consecutive % increase -

x + y + \frac{xy}{100}  ( With corresponding signs + for Increase and - for decrease)

So,  +10 - 10 +\frac{(10*-10)}{100}  =  - 1  %

Hence correct answer will be (C)  - 1  %

==>If the revenue increases by 10% from March to April, R -->R(1+10%)=1.1R, and if this decreases by 10% from April to May, 1.1R  1.1R(1-10%)=1.1R(0.9)=0.99R. If so, the revenue from March to May is R  0.99R, hence 1% decrease. The answer is C.

Vinayak Shenoy · Answer

Let the initial revenue be 100 units i.e., for the month of March
It increased by 10% in April so the new revenue is 110 units.
It decreased by 10% in May so the new revenue is 110-11= 99 units.
Percentage change in revenue from March to May = 99-100/100 = 1% decrease
Option C
