Question 13 of 20
13. Question
A, B and C went for lunch in a restaurant. A’s meal costs 60% more than that of B while the cost of the meal of A was 3/5^{th} of the meal of C. If B paid Rs. 180 for his meal, then find the average expenses of the three persons?
Correct
Answer: d)
Explanation:
Bill paid by B = Rs. 180
Bill paid by A= 180*(160/100) = Rs. 288
(3/5) of C = 288
C = 280*(5/3)
C = Rs. 480
Total bill paid by them = 288 + 180 + 480 = Rs. 948
Average expenses = 948/3 = Rs. 316
Incorrect
Answer: d)
Explanation:
Bill paid by B = Rs. 180
Bill paid by A= 180*(160/100) = Rs. 288
(3/5) of C = 288
C = 280*(5/3)
C = Rs. 480
Total bill paid by them = 288 + 180 + 480 = Rs. 948
Average expenses = 948/3 = Rs. 316
Question 14 of 20
14. Question
If the difference between the simple interest and compound interest on certain sum for 3 years at 8 % is 492.8, then find the sum?
Correct
Answer: c)
Explanation:
The difference between the simple interest and compound interest for 3 years is,
Diff = [sum*r^{2} * (r + 300)]/(100)^{3}
492.8 = [Sum*64*308]/(100*100*100)
Sum = (492.8*100*100*100)/(64*308)
Sum = Rs. 25000
Incorrect
Answer: c)
Explanation:
The difference between the simple interest and compound interest for 3 years is,
Diff = [sum*r^{2} * (r + 300)]/(100)^{3}
492.8 = [Sum*64*308]/(100*100*100)
Sum = (492.8*100*100*100)/(64*308)
Sum = Rs. 25000
