Passage
The following table shows the number of employees working in five different colleges A to E, along with the ratio of Males to Females (M:F) among them. Based on the data in the table, answer the questions that follow.
College A: 3040 employees, ratio 13:6.
College B: 3360 employees, ratio 4:3.
College C: 2920 employees, ratio 9:11.
College D: 2760 employees, ratio 10:13.
College E: 2840 employees, ratio 13:7.
If the interest received by F is Rs 7575 more than the interest received by D, and the rate of interest received by F is 2% more than the rate of interest received by A, then the interest rate received by D is:
A8%
B1.3%
C1.4%
D1.5% ✓ Correct
Correct answer: (D) 1.5% — The interest rate received by D is 1.5 percent.
Explanation
★The interest rate received by D is 1.5 percent.
★A's rate is 6 percent, so F's rate is 6 plus 2, that is 8 percent.
★F's principal is 60000 for 2 years, giving interest 60000 times 8 times 2 over 100.
★The difference between F's interest and D's interest is 7575.
★D's principal is 45000 for 3 years, so setting up the difference gives 1350 times D's rate equal to 2025.
★Solving gives D's rate as 1.5 percent.
