350
259
289
300
363
Option E
= 133 × 3 − 111 + 75
= 399 + 75 − 111
= 474 − 111
= 363

2. 41% of 801 – 150.17 = ? – 57% of 910
852
697
741
650
782
Option B
328 – 150 = 178
x – 519 = 178
x = 697

3. 69.99% of 1401 – 13.99% of 1299 = ?
977
850
798
720
777
Option C
= 70% × 1400 − 14% × 1300
= 980 − 182
= 798

4. 68.55 ÷ 0.03 + 52.8 ÷ 0.8 – 170 / 0.25 = ?
1671
1771
1881
1890
1600
Option A
6855/3 = 2285
528/8 = 66
170/0.25 = 680
2285+66 – 680 = 1671

6. Deshmukh borrows a sum of Rs.4000 at the beginning of a year. After four months Rs.2000 more is borrowed at a rate of interest double times the previous one. At the end of one year, the sum of interest on both the loans is Rs.576. What is the first rate of interest per annum?
5%
1.5%
2.4%
4.8%
3.2%
Option D
P = 4000
Rate of Interest = x
SI = 4000×𝑥×1/100 = 40𝑥
P = 6000
Rate of Interest = 2x
SI = 6000×2𝑥8/100×12 = 80x
40x + 80x = 576
x = 4.8%

7. One type of liquid contains 25% of milk, the other contains 30% of milk. A container is filled with 6 parts of the first liquid and 4 parts of the second liquid. Find the percentage of milk in the mixture.
20%
42%
25%
30%
27%
Option E
Milk in mixture
6 ×25/100 + 4 × 30/100 = 270/100
For 10 parts = 270* 10/100 = 27%

8. An order was placed for supply of carpet of breadth 3 metres, the length of carpet was 1.44 times of breadth. Subsequently the breadth and length were increased by 25 and 40 per cent respectively. At the rate of Rs. 45 per square metre, what would be the increase in the cost of the carpet ?
Rs. 725.2
Rs. 825.8
Rs. 615.4
Rs. 437.4
Rs. 520.5
Option D
Initial area of the carpet = 3 × (3× 1.44) sq. metre
= 12.96 sq. metre
After corresponding changes in dimensions, Area of the carpet
= (3*25/100)*(3*1.44*140/100)
= 22.68 sq. metre
Increase in area = (22.68 -12.96) sq. metre = 9.72 sq. metre
Increase in the cost = Rs. (9.72 × 45) = Rs. 437.4

9. An article is listed at Rs 65. A customer bought this article for Rs 56.16 with two successive discounts of which one is 10%. The other discount of this discount scheme that was allowed by the shopkeeper is
5%
4%
8%
2%
7%
Option B
Let the other discount be x% 65 × 90/100 × (100 – x)/100 = 56.16
=> 100 – x = (56.16 *100 *100)/(65 *90)
=> 100 – x = 96
x = 4%

10. A speak truth in 60% cases and B in 80% cases. In what percent of cases they likely to contradict each other narrating the same incident?

17/28
15/22
11/25
12/31

Probability = (3/5)*(1/5) + (2/5)*(4/5)
= 11/25
