(B) 30%

(C) 30.75%

(D) 27.75%

Answer key:

1. Sol. (D)

1030 – 1029 = 1029 (10 – 1)
= 9 × 1029

2. Sol. (B)

(P + 1)3 = P3 + 1 + 3P2 + 3P
P3 + 1 + 3P2 + 3P = 8
(P + 1)3 = 23
P + 1 = 2
P = 1
P2 + 2P = 1 + 2 = 3

3. Sol. (A)

AC = {5, 6, 7, 8}

4. Sol. (B)
Value/ मान = 5: 4: 3
Coins/ सिक्के = 5: 8: 12
50 paise coins/50 पैसे के सिक्के = [(225 × 8)/ 25] = 72

5. Sol. (C)

Let C can do it alone in x hours. / माना C इसे अकेले x घंटों में कर सकता है।
[(1/6) + (1/5) + (1/x)] = ½
[(5x + 6x + 30)/ 30x] = 1/2
11x + 30 = 15x
x = 7.5 hours/ घंटे

6. Sol. (D)

Ratio in profit (A: B) = 3700: 1850 = 2: 1
Investment of B = [(3600 × 12)/ (6 × 2)] = 3600

7. Sol. (A)
3300 = [(P × 10 × 3)/ 100] + [(P × 12 × 3)/ 100]
330000 = 66P
P = Rs. / रू. 5000
Total amount/कुल धनराशि = 5000 + 5000 = Rs. / रू. 10000

8. Sol. (B)

16632 = P × {1 + (5/100)} × {1 + (10/100)} × {1 + (20/100)}
16632 = P × (105/100) × (110/100) × (120/100)
P = Rs. / रू. 12000

9. Sol. (B)
a = 3021, b = 2979
ab = (3021 × 2979) = (3000)2 – (21)2
= 9000000 – 441
= 8999559



10. Sol. (A)
[15 + 15 + {(15 × 15)/100}] = 32.25%
