S2. Ans.(a) 

Sol. Cost of 10 books = Rs.(120 + 150) = Rs. 270 

Average cost = Rs. 270/10 = Rs. 27

S3. Ans.(d)

Sol. Total actual weight = (89.4 × 20 - 78 + 87) kg 

= 1797 kg.

∴ Correct average weight =1797/20 = 89.85 kg 

S4. Ans.(d)

Sol. 2400 × 12 : x × 6 : y × 3 = 4 : 5 : 3

Now 2400 × 12 = 4 in ratio 

So 7200 is 1 in ratio 

So, (x × 6)/5=7200 

x = 6000

So C share is 7200 

(y × 3)/3=7200 

y = 7200

S5. Ans.(a)

Sol. Rate of rent divide between them in the ratio of 4 : 8 : 12. So Rahul share is 8/24×9000=3000 

S6. Ans.(a)

Sol. We can find only from I 

S7. Ans.(d) 

Sol. We can’t find answer even I and II together 

S8. Ans.(e)

Sol. Both I and II required 

S9. Ans.(b)

Sol. We can find only with 2nd 

S10. Ans.(d)

Sol. We cannot find even with equation I and II  

S11. Ans.(c)

Sol. In 1980-81 is 105 while in 84-85 is 151. 

So percentage increases is ((151-105)/105)×100=(46/105)×100=43% 

S12. Ans.(d)

Sol. Total requirement = 120 + 129 + 137 + 145 + 170 = 701

Total supply = 105 + 115 + 124 + 130 + 151 = 625 

Difference = 701 - 625 = 76 

S13. Ans.(b)

Sol. 170 = 97 × x 

So, x=170/97=1.75   

S14. Ans.(d)

Sol. % Growth =(170-118)/118×100=44% 

In 1974-75 to 1979-80 growth =(118-78)/78=40/78×100=51% 

So, more = 51 - 44 = 7% 

S15. Ans.(c)

Sol. In 1979-80 demand was 118 which completed in 82-83 means 3 years.
