1.	A sells goods to B at a profit of 25%, B sells it to C at a profit of 20%, C sells it to D at a loss of 30%, if D pay Rs.2,100 for it, Find the difference between cost price of B and C.1. Rs.4002. Rs.5503. Rs.4504. Rs.5005. None of these
Answer» Correct Answer - Option 4 : Rs.500 Given: A’s profit percent = 25% B’s profit percent = 20% C’s loss percent = 30% D’s cost price = Rs.2,100 Calculation: Let, cost price for A = Rs.100x Cost price of B = {(100 + 25)/100} × 100x = Rs.125x Cost price of C = {(100 + 20)/100} × 125x = Rs.150x Cost price of D = {(100 – 30)/100} × 150x = Rs.105x = 2100 ⇒ x = 20 Cost price of B = 125 × 20 = Rs.2,500 Cost price of C = 150 × 20 = Rs.3,000 Difference of cost price of B and C = 3000 – 2500 = Rs.500 ∴ Difference of cost price of B and C is Rs.500.

Answer» Correct Answer - Option 4 : Rs.500

Given:

A’s profit percent = 25%

B’s profit percent = 20%

C’s loss percent = 30%

D’s cost price = Rs.2,100

Calculation:

Let, cost price for A = Rs.100x

Cost price of B = {(100 + 25)/100} × 100x = Rs.125x

Cost price of C = {(100 + 20)/100} × 125x = Rs.150x

Cost price of D = {(100 – 30)/100} × 150x = Rs.105x = 2100

⇒ x = 20

Cost price of B = 125 × 20 = Rs.2,500

Cost price of C = 150 × 20 = Rs.3,000

Difference of cost price of B and C = 3000 – 2500 = Rs.500

∴ Difference of cost price of B and C is Rs.500.
