Lcm of 10, 15, 18=90

90×10=900

So the least number that must be taken out is 9.

3. Answer: B

2/5×105-3/4×48=42-36=6

4. Answer: C

√196/14 × 17 /√289 × 78 /√169 =14/14×17/17×78/13=6

5. Answer: B

Let the wage be 100.

Reduced by 50%, now wage= 100-50=50

Increased by 50%, now wage = 50+25= 75

Loss=25%

6. Answer: D

28×63=?²

?=√(28×63)

=√(7x4x9x7)

=42

7. Answer: A

Profit=investment*time

Mahesh: Rajvir= 1000×3: 800×4 =15:16

Rajvir share= 620/31*16=320

8. Answer: A

Let the S.P. of the article be Rs. 100

∴ Profit on the article = Rs. 20 ∴ C.P. = 100 – 20 = 80

If C.P. is Rs. 80 then profit is Rs. 20 ∴ C.P. is Rs. 100 then profit is Rs. = 20 ×(100/80)% = 25%

9. Answer: D

Work in 1 day of Deepak = 1/12

∴ Work of 4 days of Deepak = 1/12 × 4 = 1/3

∴Theremaining work = 1 – 1/3 = 2/3

∴Both together do in 5 days = 2/3 work ∴ Both together do in 1 day = 2/(3 × 5) = 2 /15

∴ Work of 1 day of Prakash = 2/15 – 1/12 = 1/20

∴Prakash will complete the remaining (2/3) work alone in = 2/3 × 20 /1 = 13 1/3 days
