Income = Expenditure + Savings

If income of ‘B’ is ‘x%’ more than that of ‘A’, then income of ‘B’ = Income of ‘A’ × {1 + (x/100)}

If income of ‘B’ is ‘x%’ less than that of ‘A’, then income of ‘B’ = Income of A × {1 – (x/100)}

If the price of a commodity increases by ‘x%’, then percentage reduction in consumption, so as not to increase the expenditure is: [{x/(100 + x)} × 100]%

ANSWER KEYS and SOLUTIONS:

1) – C)2) – B)3) – E)4) – B)5) – D)6) – C)
7) – B)8) – D)9) – B)10) – A)

Solution 1: C)

Monthly income of Devraj = 8800/0.4 = Rs. 22000

So, (x + 5) + (x + 15) + (x – 5) = 100 – 40

3x + 15 = 60

3x = 45, x = 15

Therefore, his expenditure on Food = (15 + 15)% of 22000 = 0.3 × 22000 = Rs. 6600

Hence, option c.

Solution 2: B)

Let the monthly income of Varun = Rs. x

So the monthly income of Ankur = Rs. 0.625x

Let the monthly savings of Ankur = Rs. y

So the monthly savings of Varun = Rs. 1.6y

So the ratio of the monthly expenditures of Ankur to Varun = (0.625x – y): (x – 1.6y)

= 5(0.125x – 0.2y): 8(0.125x – 0.2y) = 5: 8

Hence, option b.

Solution 3: E)

Expenditure of Shivani = [2/(5 – 2)] × 13500 = Rs. 9000

According to question,

9000 × [100 – (x + 5) – (x + 10)]% = 4050

90 × (85 – 2x) = 4050

85 – 2x = 45

2x = 85 – 45

2x = 40

x = 20

Hence, option c.

Solution 4: B)

Let, total yearly income be Rs. 100x.

So, amount invested in FD = 0.4 × 100x = Rs. 40x

So, amount spent on rent and food = (25 + 15)% of (100x – 40x) = 0.4 × 60x = Rs. 24x

Therefore, amount saved = 100x – 40x – 24x = Rs. 36x

So, 36x = 54000

x = 54000/36 = 1500

Therefore, yearly income of Sujata = 100 × 1500 = Rs. 150000

So, monthly income = 150000/12 = Rs. 12500

Hence, option b.

Solution 5: D)

Let the monthly income of Itij be Rs. ‘x’

So, the monthly income of Akash = Rs. 1.25x

Let the monthly expenditure of Akashbe Rs. ‘y’

So, the monthly expenditure of Itij = 0.8y

So, the ratio of the monthly incomes of Akash to Itij = (1.25x – y)/(x – 0.8y)

= 5(0.25x – 0.2y)/4(0.25x – 0.2y) = 5:4

Hence, option d.

Solution 6: C)

Let monthly income of Raman and Raghav be 8x and 9x, respectively.

Then, 8x + 9x = 51000

17x = 15000, x = 3000

Raman’s monthly income = 8x = Rs. 24000

Raghav’s monthly income = 9x = Rs. 27000

Given, expenditure of Raghav = Rs. 12000

So, Raghav’s saving = 27000 – 12000 = Rs. 15000

Then, Raman’s saving = 15000 + (1/3)×15000 = 15000 + 5000 = Rs. 20000

Raman’s expenditure = 24000 – 20000 = Rs. 4000

Hence, option c.

Solution 7: B)

Monthly income of Tony = Rs. 10500

Monthly income after increase = 1.2 × 10500 = Rs. 12600

Monthly expenditure of Tony = Rs. 8000

Monthly expenditure after increase = 1.25 × 8000 =Rs. 10000

Monthly savings = 10500 – 8000 = Rs. 2500

Monthly savings after increase = 12600 – 10000 = Rs. 2600

Required percentage increase = {(2600 – 2500)/2500} × 100 = 4%

Hence, option b.

Solution 8: D)

Monthly savings of Manish earlier = 12800 – 4000 = Rs. 8,800

Monthly income of Manish now = 0.75 × 12800 = Rs. 9,600

Monthly expenditure of Manish now = 4000 – 1000 = Rs. 3,000

Monthly savings of Manish now = 9600 – 3000 = Rs. 6,600

Desired change = 8800 – 6600 = Rs. 2,200

Hence, option d.

Solution 9: B)

Monthly income of Ashok = 0.75 × 6000 = Rs. 4500

Monthly expense of Arvind = 0.5 × 6000 = Rs. 3000

Monthly savings of Arvind = 6000 – 3000 = Rs. 3000

Monthly Saving of Ashok = 4/5 × 3000 = Rs. 2400

Monthly expense of Ashok = 4500 – 2400 = Rs. 2100

Hence, option b.

Solution 10: A)

Let the salary of the Virat be Rs. x

Incentive received by him = Rs. 0.05x

Virat’s monthly income = (x + 0.05x) = Rs. 1.05x

His yearly income = 1.05x ×12 = Rs. 12.6x

According to the question,

0.25 × 12.6x = 126000

Or, x = 126000/3.15 = Rs. 40000

Incentive received by Virat every month = 0.05 × 40000 = Rs. 2000

Hence, option a.
