1. Every square should have prime factors in multiple of 2. 3150 is not divisible by 4. So there is only one 2. So we need another 2. From options it can be 2 or 14. By dividing by 7 we get 450. So there is only one 7 and we need one more. So the answer should be 14.
2. x+y=750,2x=300+y solve it.....x=350. Ans. d
3. M=16/10 *6/10=96%

1. the word proportionally gives sufficient hint that length and breadth will become 3 times (map is 2-dimensional) so area will be 3x3=9 times. hence oil paint used should be 6x9=54 lts.

2. 1/x = 1/3 - 1/3.5; so, x=21mins

3. s1 + s2 = 420/21=20; s1 - s2 = 420/42=10. so, s1=15, s2=5. Required Ratio= 3:1
