(A) Rs(2x3- 18x2 - 15)

(B) Rs(4x2 + 2x + 3)

(C) Rs(x3 - 3x)

(D) Rs(2x3 + 2x2 - 15)

Answer 1

The correct option is: (A) Rs(2x3- 18x2 - 15)

Explanation:

Total amount Raghav had = Rs(6x3 +2x2 + 3x)

Cost of one shirt = Rs(x + 5)

Number of shirts he bought = 4x2 + 3

. .. Amount spent by him = Rs(x + 5)(4x2 + 3)

= Rs(4x3 + 20x2 + 3x + 15)

Hence, money left with Raghav

= Rs(6x3 + 2x2 + 3x - 4x3 - 20x2 - 3x - 15)

= Rs(2x3 - 18x2 - 15)
