Question

a's income is 20%less than that of B. By what per cent is B's income more than A's ?

Answer 1

let the  saalary of b be rs 100
salary of a = 100-(20%of b)=100-(20*100/100)=100-20=80
a's income is 20%less than that of b by what per cent is B's income more than a's
80 + ( x % OF 80 ) =100
x * 80 / 100 = 20
x * 80 / 100 = 20
4x / 5 = 20
x= 20 * 5 / 4
x=25%

Answer 2

Answer:

The income of B is 25% more than A.

Step-by-step explanation:

Suppose,

The income of B is ₹100

So,

The income of A is (80% of ₹100)= ₹80

Gain % of B wrt A ={(100-80)/80}× 100

Gain % = 25%.

So,

The income of B is 25% more than A.
