Answer: Option D

Explanation:

Let the total number of sweets be x,

=> x = 800 * 2

=> x = 1600

44. The perimeter of a square is one-fourth the perimeter of a rectangle. If the perimeter of the square is 44 cms and the length of the rectangle is 51 cms, what is the difference between the breadth of the rectangle and the side of the square?

### Workspace

### Report Error

Answer: Option C

Explanation:

Perimeter of rectangle = 4 * 44

= 176 cm.

Width of rectangle

= (176/2) - 51 = 37 cm.

Side of square

= Perimeter/4 = 44/4 = 11 cm.

∴ Required Difference = 37 - 11 = 26 cm

45. What is the difference between the compound interest and simple interest accured on an amount of Rx. 12,000 at the end of three years at the rate of 12%?

### Answer & Explanation

### Workspace

### Report Error

Answer: Option A

Explanation:

S.I = (Principal * Time * Rate)/100

= (12000 * 3 * 12) / 100 = Rs. 4320

C.I = P[(1 + R/100)^{T} - 1]

= 12000[(1 + 12/100)^{3} - 1]

= 12000[(28/25)^{3} - 1]

= 12000[(21952/15652) - 1]

= 12000 * 6327/15625

= Rs. 4853.136

Difference = 4859.136 - 4320

= Rs. 539.136
