It was very easy.
Ans A. all expenditure=100% then, others=100-15-8-10-26-15-10. So its answer was 16%
Ans B. utilities=8/100=.08, rent=26/100=.26, food=15/100=.15
Ans C. As expenditure is 8% then, 11600*100/8=145000.
Ans D. expenditure on others in 24000 income is 24000*16/100=3840. now others include three things one is saving which ratio is 3/8. So Saving will be 3840*3/8=1440.
