A) An agent sold some carpets at the rate of Rs 4500 each and received Rs 9000 as commission at 10%. Find the number of carpets he sold.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
