Question

The number 2400 is first increased by 30%.The value obtained is next decreased by 20%.Find the final number

Answer 1

2400 is increased by 30%.

so,

2400 + (30/100 * 2400)

2400 + (30 * 24)

2400 + 720

3120

this number is decreased by 20%.

so,

3120 - (20/100 * 3120)

3120 - (2 * 312)

3120 - 624

2496

therefore, the final number will be 2496.
