Answers:

1. 4;

Ratio of profit Anil, Deepak and Sohan

= 24000 × 12 : 36000 × 7 + 36000 × 2 : 7 × 16000 + 4000

× 5

= 288 : 324 : 132

= 72 : 81 : 33

= 24 : 27 : 11

Deepak’s share of profit = 27/62 * 26164 = Rs. 11,394

2. 3;

r1 = 264 * 7/44 = 42cm

r2 = 352 * 7/44 = 56cm

Reqd difference = 22/7[(56)^2 - (42)^2]

= 22/7 * 98 * 14 = 4312

3. 2; Let the price of sugar before increase be ` x

Consumption = 15 kg

Expenditure on sugar = 15x

After increase

Expenditure on sugar = 120% of 15x = 18x

Price of sugar = 128% of x = 32x/25 per kg

New Consumption = 18x*25/32x = 14 1/16kg

4. Let Radha's savings in National Savings Certificate be x.

Then, according to the question,

x/3 = 1/2(150000 – x)

2x = 450000 – 3x

x = Rs. 90,000

Saving in Public Provided Fund

= 1, 50,000 – 90,000 = Rs. 60,000

5. 2;

Let the two-digit number be 10x + y

Numbers obtained by interchanging the digits = 10y + x

According to the question,

10x + y – (10y + x) = 54

9x – 9y = 54 x –y = 6 ... (i)

Again, y = x/3

3y = x

From (i) and (ii)

y = 3 and x = 9

Required number is 93

6. 1; Let the present age of Raju and his father be 2x and

5x respectively.

Hence, (2x + 4)/(5x + 4) = 5/11

22x + 44 = 25x + 20

3x = 24

x = 8

Father’s age 5 years ago = 5 × 8 – 5 = 35 years

7. 5

SP = Rs. 15000

If Manoj offered a discount of 10% then the new SP

= 15000 – 1500 = Rs. 13500

CP = 13500 * 100/108 = 12500

8. 4

2M = 3W

1M = 3/2W

1M + 1W = 3/2W + 1W = 5/2W

M1D1 = M2D2

3 * 4 = 5/2 * D2

D2 = 12 * 2/5 = 24/5 days

9. 3

Required number of ways

= (3C1 * 7C2) + (3C2 * 7C2) + 3C3

= (3!/2! * 7!/2!5!) + (3!!/2! * 7!/6!) + 1

(3 * 7 * 3) + (3 * 7) + 1

= 63 + 21 + 1 = 85

10. 4

Let E = Getting a king of club or queen of heart n(2) = 2

Required probablity = 2/52 = 1/26
