Reasoning

 QUANTITATIVE APTITUDE
------------------------------------------------



1) A. Sol. The mean marks of 10 boys = 70%
Total marks of 10 boys = 70% × 10 = 700
The mean marks of 15 girls = 60%
Total marks of 15 girls = 60% × 15 = 900
∴ Sum of the total marks of 25 students = 700 + 900 = 1600
∴ The mean marks of all the 25 students =1600/25=64%  

2) C.

3) C.  Total expenditure for 4 months = Rs. 2750 × 4 = Rs. 11000
Total expenditure for 3 months = Rs. 2940 × 3 = Rs. 8820   …(i)
Total expenditure of 5 months = Rs. 3130 × 5= Rs. 15650  …(ii)
Total expenditure in the whole year = Rs. 11000 + 8820 + Rs. 15650
= Rs. 35470.
Saving during the whole year = Rs. 5330
Total income of the family during the year
= Rs. 35470 + Rs. 5330 = Rs. 40800
∴ Average monthly income during the year
=40800/12= Rs. 3400

4) C

5) D  

6) B.

7) B.

8) C. Sum of weights of A, B and C = 84 × 3 kg = 252 kg
Weight of D = 4 × 80 – 252
= 320 – 252 = 68 kg
Weight of E = 68 + 3 = 71 kg
A + B + C + D = 320
B + C + D + E = 79 × 4 = 316
⇒ A – E = 4 kg
∴ A = 4 + E = 4 + 71 = 75 kg.

9) D.  The total age of 7 person = 30 × 7 = 210 years.
Total age of 5 persons = 31 × 5 = 155 years.
∴ The total age of 2 persons = (210 – 155) years = 55 years.
∴ The average age of two persons =55/2=27.5 years

10) D.
