Question

Divide ₹ 1,290 into A,B and C such that A is 2/5 of B and B :C =4:3

Answer 1

take b:c=4x :3x
since a=2/5 of b,then a=2/5×4x
a=8x/5
according to question,a+b+c=1290
then,8x/5+4x+3x=1290
43x/5=1290
x=(1290×5)/43
x=150
Now,substitute x in a,b,c
a=8x/5
a=240
b=4x
b=600
c=3x
c=450
See,it's done!

Answer 2

The answer is given below.:

Given that,

A = (2/5) B

=> A/B = 2/5

=> A : B = 2 : 5

=> A : B = 8 : 20 .....(i)

and

B : C = 4 : 3

=> B : C = 20 : 15 .....(ii)

Now, combining (i) and (ii), we get

A : B : C = 8 : 20 : 15

So, fractions for A, B and C are 8/43, 20/43 and 15/43 respectively.

Given money

= ₹ 1290

So, A will get

= ₹ (1290 × 8/43)

= ₹ 240,

B will get

= ₹ (1290 × 20/43)

= ₹ 600

and

C will get

= ₹ (1290 × 15/43)

= ₹ 450.
