Question : The compound interest on Rs. 64,000 for 3 years, compounded annually at 7.5% p.a. is:
Option 1: Rs. 14,400
Option 2: Rs. 15,705
Option 3: Rs. 15,507
Option 4: Rs. 15,075

Question : The two adjacent sides of a parallelogram are 12 cm and 5 cm respectively. If one of the diagonals is 13 cm long, then what is the area of the parallelogram?
Option 1: 60 cm2
Option 2: 30 cm2
Option 3: 75 cm2
Option 4: 25 cm2
Correct Answer: 60 cm2
Solution : In $\triangle$ABC, AB = 12 cm, BC = 5 cm and AC = 13 cm The semiperimeter ($s$) = $\frac{12+5+13}{2}$ = 15 cm So, the area of $\triangle$ABC = $\sqrt{15(15-13)(15-12)(15-5)}$ = $\sqrt{15×2×3×10}$ = 30 cm2 Now, the area of the parallelogram ABCD
