The income of C is 20% more than B’s and the income of B is 25% more than A’s. find by how much per cent is C’s income more than A’s ?

Correct answer is 50%
Let the income of B be Rs. 100

then income of C will be Rs. 120

& A’s income will be Rs 80

(Please watch video lectures for detail)

Difference between C’s & A.s income = Rs 40

hence, C’s income is frac{40}{80}times 100=50% more than A’s
