SSC CGL EXAMS 2019 | Quantitative Aptitude Questions (Day-23)

1) PQR is a triangular park with PQ = PR= 160 meter. A clock tower is situated at the mid-point of QR. The angles of elevation of the top of the tower at P & Q are Cot–1 3.2 and cosec–12.6 respectively. The height of the tower is—

a) 50 meters

b) 30 meters

c) 60 meters

d) 40 meters

2) If a, b, c, d and e are positive real numbers such that a + b + c + d + e = 30, find the maximum value of a3 b3 c6 d2 e2.

a) 225. 324

b) 224.325

c) (–6)24

d) (6)25

3) What is the reflection of the point (– 5, 3) in the line x = – 3?

a) (–2, 3)

b) (–1, 3)

c) (– 1, – 3)

d) –2, – 3

4) Two sides of a triangle are √5 – 1 & √5 + 1 units and their included angle is 60o, Solve the triangle and find the value of ‘a’?

a) √3

b) √2

c) √6

d) 2√3

5) Find the remainder of 92426/70

a) 11

b) 12

c) 9

d) 61

6) Find the last two digit of (333333)164

a) 71

b) 61

c) 51

d) 41

7) If N = a7b625, and N is divisible by 11 then how many possible pairs of values of a and b?

a) 4

b) 3

c) 2

d) Cannot be determine

8) What is the least value of 3 sin2q + 3 cos2q + 4 tan2q + 4 cot2 q + 5 sec2 q + 5 cosec2q?

a) 12

b) 13

c) 21

d) 31

9) The length of the circumradius of a triangle having sides of lengths 16 cm, 20 cm & 24 cm is

a) 32/7

b) 32 /√7

c) 4/12 * 37/188

d) 32√7/9

10) If ax + by = 8, bx –ay =2 and x2 + y2 = 4

a) 17

b) 18

c) 19

d) 20

If N is divisible by 11 then

(a + b + 2) – (7 + 6 + 5) = 0 or 11, 22

a + b + 2 – 18 = 0, 11, 22,

a + b + 2 – 18 = 0, 11, 22

a + b = 16/161+11/16+22

16/27/38

a + b = 16 (possible)

a + b = 27 / 38 etc. (Not possible, because a and b single digit number and maximum of sum of a & b for single digit = 9 + 9 = 18 = a + b = 16

(9, 7) (7, 9) & (8, 8) (8, 8) only these pairs are possible.

3 (sin2q + cos2q) + 4 tan2 q + 4 cot2 q + 5 sec2q + 5 cosec2q

= 3 + 4 tan2q + 4 cot2q + 5 (1 + tan2q) + 5 (1 + cot2 q)

=3 + 5 + 5 + (9 tan2q + 9 cot2q) min

= 13 + 2 √(9×9)

= 13 + 2 9 = 13 + 18 = 31

Given

ax + by = 8……. (i)

bx – ay = 2 ……..(ii)

We squaring on both sides on both the equation and then add it.

(ax + by)2  + (bx – ay)2 = 64 + 4

a2x2 + b2y2 + b2x2 + a2y2 + 2abxy – 2abxy = 68

x2 (a2+b2) + y2 (a2 + b2) = 68

(a2 + b2) (x2 + y2) = 68

a2 + b2 = 68/4 = 17
