Question

Rahim saves 40% of his income. His income for June was 25% less than that for May. As a result his savings for june decreased by $120. What was his income in may ? c

Answer

             Income  :  Saved

               100       :      40

                 5         :        2

              Income  :   Saved

May        100%    :    40%

June         75%    :    40/100 × 75%

                                   =  30%

40% – 30% = 10%

10% –> $120

100% –> 10 × $120

            = $1200 (Ans)

May: UUUU

June: UUU

 

Difference in income = U

Difference in savings = 40% of U = 0.4U = $120

U = $120/ (0.4) = $300

Income in May = 4U = $1200
