Rs. 4750 is divided among a, b and c in such a way that the share of c is 1/4 of the total share of a and b and the share of b is 9/10 of the share of a. what is the share of a
Answers
It is given that the amount of Rs. 4750 is divided between a, b and c only.
Let the share of a be Rs A. ... ( 1 )
According to the question, share of b is 9 / 10 of the share of a i.e. Rs A.
Therefore,
= > Share of b = 9 / 10 x Share of a
= > Share of b = 9 / 10 x Rs A
= > Share of b = Rs 9A / 10. ... ( 2 )
Given : Share of c is 1 / 4 of the total share of a and b.
Thus,
= > Share of c = 1 / 4 ( share of a + share of b )
= > Share of c = 1 / 4 ( Rs A + Rs 9A / 10 )
= > Share of c = 1 / 4 x ( Rs 10A + Rs 9A ) / 10
= > Share of c = Rs 19A / 40 ...( 3 )
Since the divided parts are of Rs 4750, there sum must be equal to Rs 4750.
= > Share of a + share of b + share of c = Rs 4750
Substituting values from ( 1 ) & ( 2 ) & ( 3 ) :
= > Rs A + Rs 9A / 10 + Rs 19A / 40 = Rs 4750
= > A + 9A / 10 + 19A / 40 = 4750
= > ( 40 A + 36A + 19A ) / 40 = 4750
= > 95A / 40 = 4750
= > A = 4750 / 95 x 40
= > A = 50 x 40
= > A = 2000
Hence the required share of a is Rs 2000.{ Since the value of a is 2000 }.
