1. ? = (84.97 *102.06)/(17.03)^2.01 + 11.9*4.9
112
100
98
90
85
Option D
? = (84.97 *102.06)/(17.03)^2.01 + 11.9*4.9
=> ? = (85*102)/(17*17)+12*5
=> ? = 30+60
=> ? = 90

2. ?^2 = 17*23 + 131 – 9^2
21
32

Option A
?^2 = 17*23 + 131 – 9^2
=> ?^2 = 391 + 131 – 81
=> ?^2 = 441
=> ? = 21

3. [18*(?^3 /5)]/3^2 + 18 = 68

Option C
[18*(?^3 /5)]/3^2 + 18 = 68
=> 18*(?^3/5)/9 = 50
=> ?^3/5= 25 =>?^3 = 125
=> ? = 5

4. ? = 47% of (14^2 + 4)+35% of (14*5*4)
192
180
177
185
199
Option A
? = 47% of (14^2 + 4)+35% of (14*5*4)
=> ? = 47% of (196+4)+ 35% of 280
=> ? = 0.47*200+ 0.35*280
=> ? = 94+98
=>? = 192

5. ? + 14 = (40% of 215 / (1369)^1/2)*3
333
300
355
398
390
Option C
? + 14 = (40% of 215 / (1369)^1/2)*3
=> ? + 14 = (86+37)*3
=> ? = 369 – 14
=> ? = 355

6. If the total number of biscuit packets of cuboidal shape each of the dimension 2.5 cm*2cm *1cm is stored in a cuboidal carton of dimensions 25 cm * 7 cm *4 cm , then find the total cost of all the biscuit packet stored in the carton if each biscuit packet costs Rs. 10.
Rs.1500
Rs.1800
Rs.1400
Rs.1200
Rs.1000
Option C
Volume of the cuboidal carton = 25*7*4 = 700 cm^3
Volume of each biscuit packet = 2.5 *2*1 = 5 cm^3
Required number of biscuit packet = 700/5 = 140
Total cost of all the biscuit packet stored in the carton = 140*10 = Rs.1400

7. If a two-digit number when increased by 20% then we get the reverse of the number. If the sum of the original number and its reverse is 99, then find the square of the original number.
2500
2025
2121
2030
2000
Option B
Let the original number be x.
Then, the reverse of the number = 1.2x x+1.2x = 99
=> x = 45
So, x^2 = 45^2 = 2025

8. The average age of 11 players of the Indian cricket team is decreased by 1 year when Ishant Sharma aged 31 years and Suresh Raina aged 28 years are replaced by two new players (Shikhar Dhawan and Bhubaneshwar Kumar). Find the average age of those new players.
15 years
24 years
27 years
18 years
20 years
Option B
Decrease in the sum of the ages of all the 11 players on replacedment = 11*1 = 11 years
Sum of the ages of the two new players = 31+28- 11 = 48 years
Average age of new players = 48/2 = 24 years

9. X deposited Rs. 800000 at 6% simple interest for 5 years whereas Y deposited Rs. 400000 at 4% compound interest for 2 years. What was the ratio of the accumulated amounts of X and Y ?
125:57
122:53
121:50
125:52
132:51
Option D
Amount for X = 800000*(1+0.06*5)= Rs. 1040000
Amount for Y = 400000*(1+0.04)^2 = Rs. 432640
Required ratio = 1040000:432640 = 125:52

10. A player gets 2 chances to roll a die in a game . He wins if the sum of the numbers obtained on the faces of the die in the two attempts is divisible by 6. What is the probability that the player wins the game?
1/3
1/5
1/7
1/6
1/8
Option D
Favourable cases
= (1,5),(5,1),(4,2),(2,4),(3,3),(6,6)
Required Probability = 6/36 = 1/6
