11—sum of ages=108
After 7 years= 108+28=136
C’s present age=136*3/8=51-7 =44

12-1176
2800-700/25*100=8400 cp
8400*140/100=1176

13.36*1/3=1/2 of b
12 =1/2 then total time taken by b is 24
1/36+1/24=72/5

14.25125
12*6  : 8*9/8*8 : 9*12
72 :72 :108
6: 6: 9=2:2:3
16750*3/2=25125

15.a.1400
20%=save
Remaining =80 %———-25%(20)clothing  remaining 75%(60)=4200
4200*100/60=7000
Saving=7000*20/100=1400
