Answer 2

Given,

£89

To Find,

Increase the given value by 61% and round off to 2 decimal points.

Solution,

We know that,

New value = 89 + Percentage increase = 89 + (61% × 89)

                  = 89 + (61% × 89) = (1 + 61%) × 89 = (100% + 61%) × 89

                  = 161% × 89 = (161 ÷ 100) × 89 = (161 × 89) ÷ 100

                  = 14,329 ÷ 100 = 143.29

Hence, £89 will become £143.29 when value is increased by 61% and round off to 2 decimal points.
