Question

a number increased by 7 percent gives 748, what is the number​

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.

7% = 7/100 = 7 ÷ 100 = 0.07.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 7% of its value.

Percentage increase = 7% × 748

New value =

748 + Percentage increase =

748 + (7% × 748) =

748 + 7% × 748 =

(1 + 7%) × 748 =

(100% + 7%) × 748 =

107% × 748 =

107 ÷ 100 × 748 =

107 × 748 ÷ 100 =

80,036 ÷ 100 =

800.36
