Question

Rs.1210 were divided among a,b,c so that
a.b = 5 : 4 and
b.c = 9 : 10. then, c gets :

Answer 1

a/b=5/4
b/c=9/10
a/b/c=45/36/40
x=1210/121
x=10
c=400

Answer 2

Answer: C would get Rs. 400.

Step-by-step explanation:

Since we have given that

Ratio of a : b = 5:4

Ratio of b : c = 9 : 10

So, ratio of a : b : c would be given by

a     :       b       :    c

5     :       4

              9       :    10

----------------------------------------------

9×5 :    4×9      :    4×10

45   :      36      :     40

Total amount would be Rs. 1210.

Amount c would get is given by

$\dfrac{40}{121}\times 1210\\\\=40\times 10\\\\=Rs. 400$

Hence, C would get Rs. 400.
