Question : 1
The average salary, per head, of all the workers of an institution is Rs.60. The average salary of 12 officers is Rs.400; the average salary, per head, of the rest is Rs.56. The total number of workers in the institution is
a) 1032
b) 1020
c) 1035
d) 1030
Answer »Answer: (a)
Number of other workers except officers = x
∴ 12 × 400 + x × 56 = (x + 12) × 60
⇒ 4800 + 56x = 60x + 720
⇒ 60x – 56x = 4800 – 720
⇒ 4x = 4080
⇒ x = $4080/4$ = 1020
∴ Total number of workers = 1020 + 12 = 1032
Question : 2
The average per day income of A, B and C is Rs.450. If the average per day income of A and B be Rs.400 and that of B and C be Rs.430, the per day income of B is
a) Rs.425
b) Rs.415
c) Rs.310
d) Rs.300
Answer »Answer: (c)
Total daily income of A, B and C = 3 × 450 =Rs.1350
Total daily income of A and B = 2 × 400 =Rs.800
Total daily income of B and C = 2 × 430 =Rs.860
∴ B’s daily income =Rs.(800 + 860 – 1350) =Rs.310
Question : 3
The average salary of all workers in a workshop is Rs.12000. The average salary of 7 technicians is Rs.15000 and the average salary of the rest is Rs. 9000. The total number of workers in the workshop is :
a) 15
b) 14
c) 13
d) 12
Answer »Answer: (b)
Total number of workers in the factory = x (let)
Number of technicians = 7
Remaining workers = x – 7
According to the question,
${7×15000+(x-7)×9000}/x$ = 12000
⇒ 7 × 15 + 9x – 63 = 12x
⇒ 105 – 63 = 12x – 9x
⇒ 3x = 42
⇒ x = $42/3$ = 14
Question : 4
The average daily income of 7 men, 11 women and 2 boys is Rs. 257.50. If the average daily income of the men is Rs.10 more than that of women and the average daily income of the women is Rs.10 more than that of boys, the average daily income of a man is
a) Rs. 257
b) Rs. 265
c) Rs. 250
d) Rs. 277.5
Answer »Answer: (b)
Average daily salary :
Men ⇒ Rs. x (let).
Women ⇒ Rs. (x – 10)
Boys ⇒ Rs. (x – 20)
According to the question,
7x + 11 (x – 10) + 2 (x – 20) = 20 × 257.5
⇒ 7x + 11x – 110 + 2x – 40 = 5150
⇒ 20x – 150 = 5150
⇒ 20x = 5150 + 150 = 5300
⇒ x = $5300/20$ = Rs. 265
Question : 5
The average monthly expenditure of a family for the first four months is Rs.2570, for the next three months Rs.2490 and for the last five months Rs.3030. If the family saves Rs.5320 during the whole year, the average monthly income of the family during the year is
a) Rs.3580
b) Rs.3200
c) Rs.3185
d) Rs.3000

=Rs.(4 × 2570 + 3 × 2490 + 5 × 3030)
=Rs.(10280 + 7470 + 15150)
=Rs.32900
Total income
=Rs.(32900 + 5320)
=Rs.38220
∴ Required average monthly income = $38220/12$ =Rs.3185
