Correct Answer: 652
Explanation:
Let the number be N.
According to the question,
N - (N x 3/4) =163
? N/4 =163
? N=652
Correct Answer: ? 1300
Explanation:
Amount after 5 yr, 4200 + (4200 x 10 x 5)/100
= (4200 + 2100) = Rs 6300
? Cost of the cow = (6300 - 5000) = ? 1300
Correct Answer: ? 9225
Explanation:
Let the loan taken be ? P Then,
[(P x 7 x 1)/100] + [(P x 7.5 x 1)/100] + [(P x 8 x 1)/100] + [(P x 8.5 x 1)/100] + [(P x 9 x 1)/100] = ? 3690
? P x (7 + 7.5 + 8 + 8.5 + 9)/100 = 3690
? (P x 40)/100 = 3690
? P = (3690 x 100)/40 = ? 9225
Hence, the loan taken was ? 9225.

Correct Answer: 63
Explanation:
| Required number of ways = (7C5 x 3C2) = (7C2 x 3C1) = | ❨ | 7 x 6 | x 3 | ❩ | = 63. |
| 2 x 1 |
Correct Answer: 72
Explanation:
So, the next number is 8 x 9 = 72.
Correct Answer: 3 : 2
Explanation:
Let the speeds of the two trains be x m/sec and y m/sec respectively.
Then, length of the first train = 27x metres,
and length of the second train = 17y metres.
| ∴ | 27x + 17y | = 23 |
| x+ y |
⟹ 27x + 17y = 23x + 23y
⟹ 4x = 6y
| ⟹ | x | = | 3 | . |
| y | 2 |
Correct Answer: 5%
Explanation:
C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
| ∴ Gain = | ❨ | 80 | x 100 | ❩% = 5%. |
| 1600 |
Correct Answer: 4
Explanation:
Unit digit in 7 95 = Unit digit in [(7 4 ) 23 x 7 3 ]
= Unit digit in [(Unit digit in(2401)) 23 x (343)]
= Unit digit in (1 23 x 343)
= Unit digit in (343)
= 3
Unit digit in 358 = Unit digit in [(34)14 x 32]
= Unit digit in [Unit digit in (81)14 x 32]
= Unit digit in [(1)14 x 32]
= Unit digit in (1 x 9)
= Unit digit in (9)
= 9
Unit digit in (795 - 358) = Unit digit in (343 - 9) = Unit digit in (334) = 4.
So, Option B is the answer.
Correct Answer:
| 54 | 6 | min. past 4 |
| 11 |
Explanation:
To be in opposite directions, they must be 30 min. spaces apart.
∴ Minute hand will have to gain 50 min. spaces.
55 min. spaces are gained in 60 min.
| 50 min. spaces are gained in | ❨ | 60 | x 50 | ❩min. or 54 | 6 | min. |
| 55 | 11 |
| ∴ Required time = 54 | 6 | min. past 4. |
| 11 |
