Quantity II: If the difference between the interest received by Himesh and Kevin is Rs. 396 and Kevin invested his money for thrice the time period for which Himesh invested his money then find the amount received by Kevin? Correct Answer Quantity I < Quantity II

Quantity I:

Rate of interest for Sohan = 6%

Let principle be Rs. x

According to the question,

x + (x × 4 × 6)/100 = 4464

⇒ 124x/100 = 4464

⇒ x = (4464 × 100)/124

⇒ x = Rs. 3600

Quantity II:

According to question

(4500 × 5 × 3x)/100 - (4800 × 12 × x)/100 = 396

⇒ (67500x - 57600x)/100 = 396

⇒ 9900x = 39600

⇒ x = 4 years

Hence Kevin invested for 12 years

Amount = 4500 + (4500 × 12 × 5)/100

⇒ Rs. 7200

Quantity I < Quantity II
