Solutions:

1.C. Distance travelled by passenger train before other train started =5*60=300
Time required to cross passenger train by other train =300/(80-60)=15 hr

2.B.Cost of 1 kg. of apples
3000/24
=125
Cost of 1 kg. of nuts
=125 x 2
= ₹250
Ritu`s annual salary
= 96 x 250 x 12
= 28800

3.C.32m…..4/9……60d
?........5/9…..20d

32*5/9*60/x*4/9*20=120
120-32=88

4. C.1/3rd at 12% loss = 1800/3 =600*88/100 =528
1800*18/100 = 324 => 1200+324+72 = 1596-1200
396 *100 /1200= 33%

5.A.130%

CP = 100, 15% GAIN = 115
SP = 230
P = 230-100 = 130
% = 130%

6. 1.32*32 = 1024
1024/4 + 19 = 256+19= 275

7.4. 261* ? -1290.76 = 536.24
261*? = 1827
? = 7
√ ? = 49

8.3. 4247.1+90.44-1664.91 = 2672.63

9.2. 1/81 * 1/6 ÷  1/9 = 9/81*6 = 1/54

10.3. a2+b2 = [(a+b)2 +(a-b)] / 2
? = 184041 + 6889
? = 95465
