Ex: Let the original no. of students be x A.T.S. 40x + 120 × 32 = (x + 120)36 ⇒ x = 120

∴ Reqd no. of students after joining the new students

= x + 120 = 240

6. The sum of two numbers is 45 and their product is 500. The G.C.M. of the numbers is:

A.5

B. 9

C. 10

D.15

Ans: A

Ex: Let the nos. be x, 45 – x A.T.S x(45 – x) = 500

x2 – 45x + 500 = 0 ⇒ x2 – 20x – 25x + 500 = 0

x(x– 20) – 25 (x – 20) = 0 ⇒ (x – 20) (x – 25) = 0

x = 25, 20. If one no. = 25 other no. = 45 – 25 = 20

G.C.M. of 25, 20 = 5

A.0.43

B.1.89

C.1.29

D.1.63

Ans: C

EX: x = √5/3 = √5*3/3*3 = √15 /√ 9 = √15/3 = 3.88/3 = 1.29

14. Of the two-digit numbers (those from 11 to 95, both inclusive) how many have a Second digit greater than the first digit?

A.37

B.38

67 to 69 — > 3

78 to 79 — > 2

89 — > 1

15. The value of (0.625 * 0.0729 * 28.9)/(0.0017 * 0.025 * 8.1) is

A.3825

B.3.825

C.38.25

D.382.5

Ans: A

Ex: The sum of decimal places in numerator and denominator being the same, decimal point can be removed

(625*729*289) / (17*25*81) = 3825

16. The size of a wooden block is 5 * 10 * 20 cm3. How many whole such blocks you will take to construct a solid wooden cube of minimum size?

A.6

B.8

C.12

D.16

Ans: B

Ex: Size of each cube = 5 cm So number of blocks = (5 * 10 * 20)/(5*5*5) = 8

17. Find the odd man out – 1050, 510, 242, 106, 46, 16, 3

A.510

B.242

C.106

D.46

Ans: C

Ex:

2nd term = (Ist term – 30) / 2 = (1050-30)/2 = 510

3rd term = (2nd term – 26) / 2 = (510-26)/2 = 242

4th term = (3rd term – 22) / 2 = (242-22)/2 = 110

So 106 is the answer.
