Question

A and B are respectively 20% and10% lower than c.What percent Of B is A

​

Answer 1

Step-by-step explanation:

Here, Z = 100, X = 80 and Y = 72

Now according to the formula,

Percentage change = (New amount - Original amount)/Original amount

= [(80 - 72)/80] x 100%

= (8/80) x 100%

= 10%

∴ Y is less by X = 10%
