Question

A boy had 450 naira left after spending 7/10 of his money.how much had he at first

Answer 1

Answer:

1500

Step-by-step explanation:

3/10th of the money he started with = 450. So he started with [(450 ÷ 3) × 10] = 150 × 10 = 1500 bucks.

Answer 2

Let the money with the man originally be x.

Given the man spends 3/8 of his money and still had 720 left with him,

=> x - (3/8)x = 720

=> [1–(3/8)]x = 720

=> (5/8)x = 720

=> x = (720 * 8)/5 = 1152
