Question : Points D, E, and F all lie on the circumference of a circle with centre O. If angle DEF = 48°, then what is a possible value of angle DOF?
Option 1: 84°
Option 2: 96°
Option 3: 90°
Option 4: 48°
Correct Answer: 96°
Solution : The points D, E, and F lie in a circle with centre O. $\angle$DEF = 48$^{\circ}$ The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle. According to the
Question : 16 women take 12 days to complete a work which can be completed by 12 men in 8 days. 16 men started working and after 3 days 10 men left and 4 women joined them. How many days will it take them to complete the remaining work?
Option 1: 4
Option 2: 6
Option 3: 8
Option 4: 10
Correct Answer: 6
Solution : Work done by 12 men in 8 days = Work done by 16 women in 12 days ⇒ 12 × 8 men = 16 × 12 women ⇒ 1 man = 2 women Now, work done by 12 men in 1 day = $\frac{1}{8}$ Work
Question : A person invested a total sum of Rs. 15,500 in three schemes of simple interest at the annual rate of 4 percent, 6 percent, and 10 percent. At the end of one year, he got the same interest in all three schemes. What is the sum invested at the rate of 6 percent?
Option 1: Rs. 5400
Option 2: Rs. 5000
Option 3: Rs. 5500
Option 4: Rs. 6500
Correct Answer: Rs. 5000
Solution : Total investment = Rs. 15,500 The annual rates of simple interest for these schemes are 4%, 6%, and 10%, respectively. Let's denote the sums invested in the schemes with rates of 4%, 6%, and 10% as P1, P2, and P
