- Question
- 150 m long train running with the speed of 90 km/h to cross a bridge in 26 s .What is the length of the bridge?
Options- A. 500 m
- B. 600 m
- C. 659 m
- D. 550 m
- Correct Answer
- 500 m
ExplanationLet length of bridge be L m.
We know, Speed = Distance/Time
According to the question,
90 x 5/18 = 150 + L/26
? 25 x 26 = 150 + L
? 650 = 150 + L
? L = 500 m - 1. If log 64 = 1.8061, then the value of log 16 will be (approx)?

Correct Answer: 1.2040
Explanation:
Given that, log 64 = 1.8061
i.e
--> 3 log 4 = 1.8061
--> log 4 = 0.6020
--> 2 log 4 = 1.2040
Therefore, log 16 = 1.2040
Correct Answer: 176
Explanation:
99 = 1 x 3 x 3 x 11
101 = 1 x 101
176 = 1 x 2 x 2 x 2 x 2 x 11
182 = 1 x 2 x 7 x 13
So, divisors of 99 are 1, 3, 9, 11, 33, .99
Divisors of 101 are 1 and 101
Divisors of 176 are 1, 2, 4, 8, 11, 16, 22, 44, 88 and 176
Divisors of 182 are 1, 2, 7, 13, 14, 26, 91 and 182.
Hence, 176 has the most number of divisors.
Correct Answer: 20
Correct Answer: Monday
Correct Answer: 50 2/7 sq.cm
Correct Answer: Friday
Correct Answer: -19
Explanation:
HCF of 210 and 55 is 5
Now, 210x5 + 55P = 5
=> 1050 + 55P = 5
=> 55P = -1045
=> P = -1045/55
=> P = -19.
