Question : 11 [SSC CGL Prelim 2004]
A man spends a part of his monthly income and saves a part of it. The ratio of his expenditure to his saving is 26 : 3. If his monthly income is Rs.7250, what is the amount of his monthly savings ?
a) Rs.750
b) Rs.780
c) Rs.290
d) Rs.350
Answer »Answer: (a)
Let his expenditures be Rs.26x
and savings be Rs.3x.
26x + 3x = 7250
29x = 7250
$x = 7250/29$ =250
Savings = 3x = Rs.750
Question : 12 [SSC CHSL 2010]
The monthly salaries of A, B and C are in the ratio 2 : 3 : 5. If C’s monthly salary is Rs.12,000 more than that of A, then B’s annual salary is
a) Rs.1,80,000
b) Rs.2,40,000
c) Rs.1,44,000
d) Rs.1,20,000
Answer »Answer: (c)
Let the monthly salary of A, B & C be 2x, 3x and 5x
now, 5x - 2x = 12,000
3x = 12000 or x = 4000
Monthly salary of B
= 3 × 4000 = 12,000
Annual salary of B
= 12000 × 12 = Rs.144000
Question : 13 [SSC CGL Tier-I 2010]

c) Rs.8,800
d) Rs.8,000
Answer »Answer: (b)
Let the income of man be = Rs.11x
and his expenditure be Rs.10x.

Monthly income of man

Question : 14 [SSC CGL Tier-II 2017]
A’s income is Rs.140 more than B’s income and C’s income is Rs.80 more than D’s. If the ratio of A’s and C’s incomes is 2 : 3 and the ratio of B’s and D’s incomes is 1 : 2, then the incomes of A, B, C and D are respectively
a) Rs.400, Rs.260, Rs.600 and Rs.520
b) Rs.320, Rs.180, Rs.480 and Rs.360
c) Rs.300, Rs.160, Rs.600 and Rs.520
d) Rs.260, Rs.120, Rs.320 and Rs.240
Answer »Answer: (a)
Let A‘s income be Rs.2x.
B’s income = Rs.(2x - 140)
C’s income = Rs.3x
D’s income = Rs.(3x - 80)
According to the question,
B : D = 1 : 2
2 (2x - 140) = 3x - 80
4x - 280 = 3x - 80
4x - 3x = 280 - 80
x = Rs. 200
A’s income
= Rs.(2 × 200) = Rs.400
B’s income
= Rs.(400 - 140) = Rs.260
C’s income
= Rs.(3 × 200) = Rs.600
D’s income
= Rs.(600 - 80) = Rs.520
Question : 15 [SSC CGL Tier-I 2013]
The ratio of monthly incomes of A, B is 6 : 5 and their monthly expenditures are in the ratio 4 : 3. If each of them saves Rs.400 per month, find the sum of their monthly incomes.
a) 2200
b) 2500
c) 2400
d) 2300
Answer »Answer: (a)
Income of A and B
= Rs.6x and 5x
Expenses of A and B
= Rs.4y and 3y
6x - 4y = 400 ...(i)
5x - 3y = 400 ...(ii)
By equation (i)× 3 - (ii) × 4
18x - 12y - 20x + 12y
= 1200 - 1600
2x = 400 ⇒ x = 200
Total income
= 6x + 5x = 11x = Rs.2200
