Question

vinod and his two daughters samridhi and khayati purchase a car for rs. 525000 samridhi contributes 3upon 5 of her father contribution while khayati 1upon2 contributes of her father contribution. how much do three contribute individually

Answer 1

Let fathers Contri. be X
now samridhis contribution = (3/5)x
and khayati's contribution = (1/2)x
total contribution = x + (3/5)x +(1/2)x ---eq 1
also total contribution = 525000 --- eq 2
equate both the equatuons
525000=x + (3/5)x +(1/2)x
525000 = (10x+6x+5x)/10. (after L. C. M)
525000*10 = 10x+6x+5x
5250000 = 21x
x = 5250000/21
x = 250000
fathers Contri. x = 250000
now samridhis contribution = (3/5)x = (3/5)*250000 = 150000
and khayati's contribution = (1/2)x = (1/2)*250000 = 125000
