Total Questions: 50

1. Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.

252 * 9 * 5 * 32 * 92 = 200

Correct Answer: C. ÷, ×, -, +
Solution:Given equation: 252 * 9 * 5 * 32 * 92 = 200
After sequentially replacing the * by ÷, ×, - and + we get
252 ÷ 9 × 5 − 32 + 92 = 200
28 × 5 − 32 + 92 = 200
140 − 32 + 92 = 200
200 = 200
Hence, correct option is (C).

2. Study the given pattern carefully and select the number that can replace the question mark (?) in it.

Correct Answer: B. 18
Solution:
3               (3 + 5) × 2 − 3 = 13 5
11(11 + 4) × 2 − 3 = 27 4
21(21 + 18) × 2 − 3 = 75x

Here, (21 + x) × 2 - 3 = 75
21 + x = 75+3/2
∴   x = 39 - 21 = 18.

3. Select the option in which the numbers are related in the same way as are the numbers in the given set.

(5, 17, 49)

Correct Answer: D. (8, 23, 67)
Solution:Here given triplet
(5, 17, 49) is related to the triplet given in option (D) (8, 23, 67).

4. Three different positions of the same dice are shown, the six faces of which are numbered from 1 to 6. Select the number that will be on the face opposite to the one showing '3'.

Correct Answer: D. 4
Solution:From given dice position (ii) and (iii)
Side faces '1' and '4' remains same, when top faces shows '2' and '6'.
So, 2 is opposite to 6.
Again from position (i), adjacent to '3' is '1' and '2' and so '6' also.
∴ Opposite to '3' is either '4' or '5'.
From dice positions (i) and (iii)
Faces adjacent to '2' are 1, 3 and 4
Hence, '4' is opposite to '3'.
