Correct Answer: 22000
Correct Answer: 2.36
Correct Answer: 2065.2
Correct Answer: 8
Correct Answer: 16000
Correct Answer: Rs 13400
Correct Answer: 10 percent
Correct Answer: 38
Explanation:
Let the number of correct answers be X.
Number of incorrect answers = (60 ? X).
4x ? (60 ? x) = 130
=> 5x = 190
=> x = 38
Correct Answer: 1000
Explanation:
Let the cost of a table and that of a chair be Rs. x and Rs, y respectively.
Then, 2x + 3y = 3500 ...(i)
and 3x + 2y = 4000 .....(ii)
solving (i) and (ii) we get x = 1000, y = 500
Correct Answer: 30 birds
Explanation:
Let the no of shots be x. Then,
Shots fired by A =(5/8)x
Shots fired by B = (3/8)x
Killing shots by A = 1/3 of (5/8)x = (5/24)x
Shots missed by B = 1/2 of (3/8)x = (3/16)x
(3/16)x = 27 x =144
Birds killed by A = (5/24)x = (5/24)*144 = 30
