1. The average score of a cricketer for 13 matches is 42 runs. If his average score for the first 5 matches is 54, then what was his average score (in runs) for last 8 matches?
1. 37
2. 39
3. 34.5
4. 33.5
5. 37.5
Total Score = Average * Number of matches
Total score of 13 matches = 13 × 42 = 546
Total score of first 5 matches = 5 × 54 = 270
Therefore, total score of last 8 matches = 546 – 270 = 276
Average = 276/8 = 34.5
Hence the answer is option C
2. Simple interest on a sum of money for 4 years at 7 p.c.p.a is Rs. 3584/-. What would be the compound interest (compounded annually) on the same amount of money for 2 years at 4p.c.p.a?
1. Rs. 1,162.32
2. Rs. 1,098.72
3. Rs. 992.38
4. Rs. 1,231.76
5. Rs. 1,044.48
Let P be the sum
Therefore,
3584 = (P * 7 * 4) / 100 => P = 12800/-
CI = 12800(1 + (4/100))2 - 12800
=> 13844.48 - 12800 = 1044.48/-
Hence the answer is option E
1. 6*136/8+132 / 628/16-26.25=?
1. 15
2. 24
3. 18
4. 12
5. 28
6*136/8+132 / 628/16-26.25
⇒ 234/13=18 Hence the answer is option C.
2. (1331)1/3/ 275 *52 = ?
1. 2
2. 4
3. 1
4. 2.5
5. 3
? = (1331)1/3/275 *(5)2
= (113)1/3 / 11*25 *(25)
=1 Hence the answer is option C.
3. (43)2 + 841 = (?)2 + 1465
1. 41
2. 35
3. 38
4. 33
5. 30
Using BODMAS
(?)2 = (43)2 + 841 – 1465
= 1849 + 841 – 1465 = 1225
Therefore, ? = √1225 = 35
Hence the answer is option B
4. (216)4 ÷ (36)4 × (6)5 = (6)?
1. 13
2. 11
3. 7
4. 9
5. 10
(6)? = (216)4 ÷ (36)4 × (6)5 =
2164/364 * 65 =
612 / 68 * 65=
69 Therefore, ? = 9
5. (1097.63 + 2197.36 - 2607.24) ÷ 3.5 = ?
1. 211.5
2. 196.5
3. 209.5
4. 192.5
5. 189.5
? = (1097.63 + 2197.36 - 2607.24) ÷ 3.5 = 687.75 ÷ 3.5
= 196.5
Hence answer is option B
6. A certain number of capsules were purchased for Rs. 216/-. 15 more capsules could have been purchased in the same amount if each capsule was cheaper by Rs. 10/-. What was the number of capsules purchased?
1. 6
2. 14
3. 8
4. 12
5. 9
Let x be the cost of each capsule and y be the no of capsules
Therefore, x = 216/y and x - 10 = 216/(y+15)
Putting the value of x from eq. 1 into eq. 2, we get
216/y - 216/(y+15) = 10
y2 +15y - 324 = 0
Solving for y, we get y = 12
Hence answer is option D.
7. What will come in place of question mark (?)in the given question?
4 6 34 ? 504 1234
1. 194
2. 160
3. 186
4. 156
5. 172
Here the difference between each term is in the form of 13+1, 33+1, 53+1, 73+1 and so on
4 6 34 160 504 1234
+2 +28 +126 +344 +730
13 + 1 33 + 1 53 + 1 73 + 1 93 + 1
So ? = 160
Hence answer is option B
8. A and B are two numbers. 6 times square of B is 540 more than the square of A. if the respective ratio between A and B is 3:2. What is the value of B?
1. 10
2. 12
