Question

A pair of boots costs $50 and a certain coat costs $150. If the price of the boots is decreased by 20% and the price of the coat is decreased by 30%, which of the following is the sum of their new costs?

$165

$200

$225

$265

$330

Answer 1

20% of 50= 20/100*50= 0.2*50= 10
new cost of it = 50-10=$40
similarly 30% of 150 = 0.3*150=45
new cost of coat= 150-45=$105
and total new sum=105+40=$145

Answer 5

20% of 50= 0.2*50= 10
so new cost is 50-10=40
similarly 30% of 150= 0.3*150= 45
new cost is = 150-45=105
total new cost = 105+40=$ 145

Answer 17

"If the answers are right, which OP insists, then the question may not be.
Example:
A pair of boots costs $50 and a certain coat costs $150. If the price of the boots is decreased by 10% and the price of the coat is decreased by 20%, which of the following is the sum of their new costs?"
would give $165.
