102% 105% 120% 135% 140%


Easiest thing to do: Assume that price is 100

Price at the end of yr 1: 100+ 20 = 120

Price at the end of year 2 = 120 - 120*0.15 = 120*0.85 = 102

Hence required answer = (102/100)*100% = 102%

Answer is A.

But to find % formula is difference by original *100

so it should be like (102-100/100)*100


Pls suggest

Hi

See, in short the question asks: "What % of 100 is 102"?

If it were, "What is the % change from 100 to 102", then your answer would suffice.

Regards,

Shouvik.

Apply successive percentage change
a+b+ab/100
=20-15-300/100
= 2%
so my answer is A i.e. 102%
