Ali is twice as old as his youngest brother. If the difference between their ages in 15 years, how old is his youngest brother?
- 10
- 15
- 20
- 25
- b
-
Ali is twice old as his youngest brothr
Age difference never changes, after 15 years, both will increase by 15, so the difference will remain the same.
If Youngest brother is X
Then, Ali is 2x
2x – x= x
Given Difference= 15
X=15
The speed of a car is 30 km in the first hour and 32 km in the second hour. Its average speed is:
- 30 km
- 31 km
- 32 km
- None of these
- b
-
Distance in First hour is 30 Km
Distance in Second hour is 32 Km
Total Distance=30+32=62 km
Total Time=1+1=2 hrs
Average Speed=Total Distance / Total Time
Average Speed= 62/2=31 km/h
Which is the greatest number?
- 1/6 of 1028
- 1/3 of 741
- 1/4 of 236
- None of these
- b
-
1/6*1028=171.33
1/3*741=247
1/4*236=59
5 men can do work in 50 days. How long will it take 3 men to complete the work?
- 83 days
- 85 days
- 90 days
- None of these
- a
-
5 men can do work=50 days
We need to find how long 3 men will take time?
Total Work= 50*5=250
Time = Total Work / No. of Men
Time =250 / 3 = 83.33 days
If the cost of a loaf is Rs.5.50, what is the cost of 2-1/2 loaves of bread?
- Rs. 13.75
- Rs. 15.75
- Rs. 11.75
- None of these
- a
-
Cost of 1 Loaf =5.50
Cost of 2-1/2 Loaf =5.50 * 2 – 1/2= 13.75
What percentage of 720 is 36?
- 15%
- 10%
- 5%
- None of these
- c
-
720/36 * 100
0.05*100=5%
Divide the largest of following numbers by the difference of two small numbers, then the answer will be: 16 20 12
- 2
- 5
- 4
- 10
- b
-
Largest number is 20
Smallest numbers are 16 and 12
Difference of Two smaller number is 4
Largest No / Difference= 20/4=5
If 3x-5=x+11, then x=?
- 2
- 6
- 8
- 12
- c
-
3x – 5 = x +11
3x – x = 11 + 5
2x = 16
x=16/2
x=8
The cost of 5 chairs in Rs.2000. The cost of 12 chairs will be:
- 4800
- 5600
- 6400
- 6450
- a
-
Cost of 5 Chairs=2000
Cost of 1 Chair=2000/5=400
Cost of 12 Chairs=12*400=4800
