1. 300%
2. 200%
3. 800%
4. 600%

Answers:

1.Answer: B

Per day work of Arvind = 1/15

Per day work of Gokul = 1/30

Per day work of Arvind + Gokul= 1/15 + 1/30 = 3/30 = 1/10

The whole work completed in 10 days

2.Answer: C

350/100*700= 2450

500/100* 450= 2250

2450+2250 = 4700

3.Answer: B

 

 

4.Answer: C

Surface Area of Cuboid = 2(lb + lh + bh)

= 2 (40 x 24 + 40 x 12 + 24 x 12)

= 2(960 + 480 + 288)

= 2 x 1458 =  2916

Hence, Surface Area of 100 suitcases = 291600 sqcms

Required tarpaulin will have same area = Area/ Width

= 291600/ 90 = 3240 cm=3240/100 m=32.40 m

5.Answer: A

6.Answer: A

Let the ages of Akash and Baskar be5x and 4x respectively.

(5x+3)/(4x+3)=11/9

X=6

Age Of Baskar= 6*4=24

7.Answer: B

170 is the least number is to added to make 7399 a perfect square.

9.Answer: B

1, 9, 8, 6, 10, 15, 17

1,6,8,9,10,15,17

Median = 9

10.Answer: c
