- Question
- Find the compound interest for a sum of ? 9375 in 2 yr, if the rate of interest for the first year is 2% and for the second year is 4%.
Options- A. ? 570
- B. ? 670
- C. ? 770
- D. ? 760
- Correct Answer
- ? 570
ExplanationGiven, P = ? 9375, R1 = 2% and R2 = 4%
According to the formula,
A = P (1 + R1/100) (1 + R2/100)
= 9375 (1 + 2/100) (1 + 4/100)
= 9375 x (51/50) x (26/25)
= 7.5 x 51 x 26
= ? 9945
Now CI = A - P = 9945 - 9375 = ? 570 - 1. The banker's discount on Rs. 1800 at 12% per annum is equal to the true discount on Rs. 1872 for the same time at the same rate. Find the time.

Correct Answer: 4 months
Explanation:
S.I. on Rs. 1800 = T.D. on Rs. 1872.
P.W. of Rs. 1872 is Rs. 1800.
Rs. 72 is S.I. on Rs. 1800 at 12%.
Time =[(100 x 72)/ (12x1800)]year
=1/3year = 4 months.
Correct Answer: 236
Correct Answer: 1452
Correct Answer: 229
Correct Answer: 15.5
Correct Answer: 25? sq cm
Correct Answer: 2:3
Explanation:
Let the number of boys = b
Let the number of girls = g
From the given data,
81b + 83g = 81.8(b + g)
81.8b - 81b = 83g - 81.8g
0.8b = 1.2g
b/g = 1.2/0.8 = 12/8 = 3/2
=> g : b = 2 : 3
Hence, ratio between the number of girls to the number of boys = 2 : 3.
Correct Answer: 21 km
Explanation:
Let the distance covered be D km.
10D = 42 x 5 = 210
=> D = 21 km
Correct Answer: 1020
Explanation:
T.D. =(B.G*100)/(R*T)=Rs(270*100)/(12*3) = Rs. 750.
B.D. = Rs.(750 + 270) = Rs. 1020.
Correct Answer: 45(?3+2)
