Answer: Option B
Explanation:
Unit digit in 795 = Unit digit in [(74)23 x 73]
= Unit digit in [(Unit digit in(2401))23 x (343)]
= Unit digit in (123 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.

Answer: Option D
Explanation:
| Angle traced by hour hand in | 125 | hrs = | 360 | x | 125 | ° | = 312 | 1 | ° | . | ||
| 12 | 12 | 12 | 2 |
| Angle traced by minute hand in 25 min = | 360 | x 25 | ° | = 150°. | ||
| 60 |
| Reflex angle = 360° – | 312 | 1 | – 150 | ° | = 360° – 162 | 1 | ° | = 197 | 1° | . | ||

Answer: Option A
Explanation:
Unit digit in (6374)1793 = Unit digit in (4)1793
= Unit digit in [(42)896 x 4]
= Unit digit in (6 x 4) = 4
Unit digit in (625)317 = Unit digit in (5)317 = 5
Unit digit in (341)491 = Unit digit in (1)491 = 1
Required digit = Unit digit in (4 x 5 x 1) = 0.
A. Rs 230
B. Rs 232
C. Rs 600
D. Rs 832
Explanation:
S.I = Rs (6000 × 5/100 × 2) = Rs 600
C.I = Rs [5000 × (1 + 8/100)2 – 5000]
= Rs (5000 × 27/25 × 27/25 – 5000)
= Rs(5832 – 5000)
= Rs 832
(C.I) – (S.I) = Rs (832 – 600) = Rs 232

[D].
Answer: Option B
Explanation:
Let rate = R% and time = R years.
| Then, | 1200 x R x R | = 432 | ||
| 100 |
12R2 = 432
R2 = 36
R = 6.
