- 60 kmph
- 48 kmph
- 12 kmph
Answers:
1.Answer: C
P – 1/60 Q – 1/30 R- 1/120
P+Q+R = 1/60 + 1/30 – 1/120 =(2+4 – 1)/120 = 5/120 = 24 mins
2.Answer: A
8888+888+88+8 = 9872
3.Answer: B
LCM of 5, 6, 7 and 8 = 840
Required number = (840k + 3) which is divisible by 9.
Now, 840k +3 = 93 ×9K +(3k+3)
When k = 2, 3K+3 =9, which is divisible by 9
∴Required number = 840 ×2 +3 = 1683
4.Answer: c
√2722 – 1282 = √(272 – 128)(272+128)
= √(400×144) =√(20×20×12×12 )= 20×12 = 240
5.Answer: B
6.Answer: C
(1,25,00× 100)/125 = 10,00,00
7.Answer: D
tan5°.Tan45°. 4 tan 85° = (tan90 – 5°) .tan 45°. 4 tan 85°
= cot 85°. 4 tan 85° .tan 45°
=4(1). 1 = 4
8.Answer: B
The measure of each interior angle of a regular polygon is always 180(n — 2)/n degrees, where n represents the number of sides of the polygon. The measure of each exterior angle of a regular polygon is 360/n degrees
9.Answer: C
280 + 45% 0f 300 + 5x – 300
= 280 + 135 + 5x – 300 = 415 – 300 +5x
5x =115
X = 23
10.Answer: C
Average speed = (2xy)/x + y
= (2 × 40 ×60) / 100
= 4800/100 = 48
