Correct answer

Answer: (b)B.

C

Why this answer is correct

Given:

Principal, P = Rs. 550

Rate of interest = 5%

Time = 4 years

Formula used:

S.I. = P × R% × T

Amount = P + S.I.

Calculation:

S.I. = P × R% × T

⇒ S.I. = 550 × 5/100 × 4

⇒ S.I. = Rs. 110

Amount = P + S.I.

⇒ Amount = 550 + 110

⇒ Amount = Rs. 660

∴ She will have to pay Rs. 660.

View answer & explanation

Correct answer

Answer: (c)C.

A

Why this answer is correct

Given:

Profit% = 4%

Increased profit% = 10%

Difference = Rs. 3

Concept used:

SP = (100 + Profit%) of CP

Calculation:

Let the CP of an item be Rs. x.

Required difference = SP at 10% – SP at 4%

⇒ 3 = (100 + 10)% of x – (100 + 4)% of x

⇒ 3 = 110/100 × x – 104/100 × x

⇒ 3 = x(110 – 104)/100

⇒ 300 = 6x

⇒ x = Rs. 50

SP at 4% = (100 + 4)% of x

⇒ SP at 4% = 104/100 × 50

SP at 4% = Rs. 52

SP at 10% = (100 + 10)% of x

⇒ SP at 10% = 110/100 × 50

⇒ SP at 10% = Rs. 55

Required ratio = SP at 4% ∶ SP at 10%

⇒ Required ratio = 52 ∶ 55

∴ The ratio of the selling price of both is 52 ∶ 55.
