Question

Johny save 15% of his earnings each month. In January he
got 32000 rupees. How much would he save?​

Answer 1

Answer:

Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

15% = 15/100 = 15 ÷ 100 = 0.15.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 15% of its value.

Percentage increase = 15% × 32,000

New value = 32,000 + Percentage increase

Calculate the New Value

New value =

32,000 + Percentage increase =

32,000 + (15% × 32,000) =

32,000 + 15% × 32,000 =

(1 + 15%) × 32,000 =

(100% + 15%) × 32,000 =

115% × 32,000 =

115 ÷ 100 × 32,000 =

115 × 32,000 ÷ 100 =

3,680,000 ÷ 100 =

36,800

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 32,000 =

36,800 - 32,000 =

4,800
