Question
The average Cost Price of two items P and Q is Rs. 500.
P and Q are sold at 15% and 25% profit respectively. If the total Selling Price of P and Q is Rs. 1,185, then find the Cost Price of Q.Solution
Total CP of P and Q together = 500 × 2 = Rs. 1,000
Let CP of P = x ⇒ CP of Q = (1,000 – x)
ATQ:
115% of x + 125% of (1,000 – x) = 1,185
1.15x + 1,250 – 1.25x = 1,185
–0.10x = –65
x = 650
CP of Q = 1,000 – 650 = Rs. 350
