Answer 1

Step-by-step explanation:

a number whose 80% is 528

the number is

100/80 × 528

660

Ans

second method:-

let the number is x

then,

80% of x = 528

80/100 × x = 528

multiply both sides by 100/80

80/100 × x × 80/100 = 528 × 100/80

in LHS , 80/100 and 80/100 cancel out

x =100/80 × 528

x =660
