Question 3 .......

1. Let m be the number.

After 20% deduction, the number becomes (4/5)m.

30% of Remainder = (3/10)x(4/5)m = (12/50)m = (6/25)m.

Remaining = (19/25)m.

(19/25)m=3500.

m = 4605 approximately.

Therefore, original sum is 4605 approximately.

But My ans Is

after 20% deduction number become 80m\100 , then 30 % deduction from 80m\100 number become 50m\100

So 50m\100 =3500 so m = 7000

How original price is ,120\100 *120 ?

Question 2 steps show

Your ans is different

So 50m\100 =3500 so m = 7000
