A certain sum is divided among A, B and C in such a way that A gets 35 more than the 2/5 of the sum and B gets 75 less than the 1/5 of the sum and C gets Rs. 350. Find the sum.
A900
B810
C780
D775
Answer:
D. 775
Read Explanation:
Let total sum be x,
A= (2/5)x +35
B = (1/5)x – 75
C= 350
A+B+C =x
(2/5)x +35 + (1/5)x – 75 +350 =x
(3/5)x +310 = x
310 = x- (3/5)x
(2/5)x = 310
x= 310*(5/2) = 775
