Correct Answer: 300
Explanation:
Required number = = 75 x 4 = 300
Correct Answer: 175
Explanation:
Suppose the man works overtime for x hours.
Now, working hours in 4 weeks = (5 x 8 x 4) = 160.
Therefore, 160 * 2.40 + x * 3.20 = 432
=> 3.20x = 432 - 384 = 48
=> x = 15.
Hence, total hours of work = (160 + 15) = 175.
Correct Answer: None of these
Explanation:
After solving we get,
62/931.
None of the options satisfy.
Correct Answer: 35 litres
Explanation:
Let the capacity of the tank be x litres.
Then, (6x/7 - 2x/5) = 16 <=> 30x - 14x = 16*35 <=> x = 35
Correct Answer: 62.5
Correct Answer: 10
Explanation:
Apply
Hence the answer is 1.5 + 4.7 + 3.8 = 10.
Correct Answer: 121
Explanation:
Let the score be x. Then the highest score = 3x/11.
Reminder = (x - 3x/11) = 8x/11 .Next the highest score = 3/11 of 8x/11 = 24x/121.
3x/11 - 24x/11 = 9 <=> 33x - 24x = 9*121 <=> x= 121..
Correct Answer: 166252
Explanation:
Given
Using unit digit method,
On LHS,
1 x 1 x 1 = 1
sqrt of last digit 1 => it must end with either 9 or 1
so now
1 x 1 = 1
1 x 9 = 9
On RHS,
? + 89
=> ? = ...1 - 89 = last digit is 11- 9 = 2
or
=> ? = ...9 - 89 = last digit is 9 - 9 = 0
Here in the options last digit 2 is option C.
Correct Answer: 70000
Explanation:
= 70,000.
Correct Answer: 12
Explanation:
Let the number of buffaoes be x and number of ducks be y.
Then 4x + 2y = 2(x + y) + 24
=> 2x = 24
=> x = 12.
