- Question
In an election between two candidates 70% of the voters cast their votes, out of which 2% of the votes were declared invalid. A candidate got 7203 votes which was 60% of the total valid votes. Find the total number of voters enrolled in that election.
Options- A. 18050
- B. 17500
- C. 17000
- D. 7203
- Correct Answer
- 17500
ExplanationLet total number of votes enrolled = x
No. of voted cast = 70% of x = 0.7x
Valid votes = 98% of 0.7x
? 60% of total valid votes = 7203 = 60% of 98% of 0.7x
? 0.6 X 0.98 X 0.7x = 7203
? x = 7203 / (0.6 X 0.98 X 0.7)
? x = 17500 - 1. Which of the following is not a leap year?

- B. 1200
- C. 1600

Correct Answer: 2100
Explanation:
The century divisible by 400 is a leap year. 2100 is not divisible by 400 hence is not a leap year.
Correct Answer: Rs. 60000
Explanation:
? Cost of 6 dozen chairs = 6 x 12 x214 = Rs. 15408
And cost of 4 dozen tables = 4 x 12 x 937 = Rs. 44976
? Total cost =15408 + 44976
= Rs. 60384
= Rs. 60000 (Approximately)
Correct Answer: 116
Explanation:
? = 783/9 x 0.75 = 116
Correct Answer: Rs. 2500
Explanation:
Correct Answer: 1000
Explanation:
724 ÷ 25 x 31.05 + 101 = ?
? ? = 725 ÷ 25 x 31 + 101
= 29 x 31+ 101
= 899 + 101 = 1000
Correct Answer: 1400 m
Explanation:
Speed of train in m/sec = (speed of train in km/hr) x 5/18
? speed of train in m/sec = 54 x 5/18 = 15 m/sec
Time taken to cross the tunnel = 2 minutes = 120 sec
Therefore, Total length covered by train in crossing the tunnel = Speed of train x Time taken to cross the tunnel
= 15 m/sec x 120 sec = 1800 m
Now, we know that
Total length covered by train in crossing the tunnel = Length of train + Length of tunnel
Given, Length of train =400m and
Calculated above, Length covered by train in crossing the tunnel = 1800 m
Therefore, Length of tunnel = 1800m- 400m = 1400m
Correct Answer: 10 gms
Explanation:
If the two alloys are mixed, the mixture would contain 15 gms of each metal and it would cost Rs. (150 + 120) = Rs. 270.
Cost of (15 gms of metal A + 15 gms of metal B) = Rs. 270
Cost of (1 gm of metal A + 1 gm of metal B) = Rs. (270 / 15) = Rs. 18
Cost of 1 gm of metal B = Rs. (18 ? 6) = Rs. 12
Average cost of original piece of alloy = (150 / 15) = Rs. 10 per gm.
Quantity of metal / A Quantity of metal B = (2 / 4) = (1 / 2)
Quantity of metal B = 2 (1 + 2) × 15 = 10 gms.
Correct Answer: 7.2
Explanation:
| Speed = | ❨ | 600 | ❩m/sec. |
| 5 x 60 |
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
| = | ❨ | 2 x | 18 | ❩ | km/hr |
| 5 |
= 7.2 km/hr.
Correct Answer: 56 m
Explanation:
According to the question, A : B = 200 : 150
and B : C = 200 : 192
? A : C = (A/B) x (B/C) = (200/150) x (200/192) = 200/144
So, A beats C by (200 - 177) = 56 m
Correct Answer: 3400
Explanation:
26.823 x 27.923 x 4.5001
? 27 x 28 x 4.5000 = 756 x 4.5000 = 3402 ? 3400
