Answer 1

75% of 5% is 1687.50

100% of 5% is 2250

it is the amount he wanted to donate ( i.e, 5%)

5% ------- 2250

100%-------?

100*2250/5=45000 rs

Answer 2

Answer:

let the salary be 100%

It is given that he decided to donate 5% of the salary , then

salary left :- 100- 5 = 95%

on the day of donation he changed his mind and donated rs .1687.50 which was 75% of what he had decided earlier.

let think that 5% = X then,

X× 75/100 = 1687.50

X= 1687.50× 100/75

X = 2250

it means 5% = 2250

then 1% = 2250/5

1% = 450

if 1% = 450

then 100% = 100× 450

= 45000

hence rishu's salary was $45000 .
