The denominator of a fraction is 2 more than the numerator. If the numerator as well as the denominator is increased by 4, the fraction becomes 13/15. What was the original fraction?

Correct

Answer – 3) 9/11
Explanation:
Let the numerator be x Then, denominator = x + 2.
Now. (x + 4)/(x + 2) + 4 =13/15
15 (x + 4) = 13(x + 6)
=> x = 9
original fraction = 9/11.

Incorrect

Answer – 3) 9/11
Explanation:
Let the numerator be x Then, denominator = x + 2.
Now. (x + 4)/(x + 2) + 4 =13/15
15 (x + 4) = 13(x + 6)
=> x = 9
original fraction = 9/11.

A watercraft takes 11 hours for travelling downstream from point P to point Q and coming back to a point R which is at midway between P and Q. If the velocity of the stream is 4 kmph and the speed of the boat in still water is 16 kmph, what is the distance between P and Q?

Correct

Answer – 4) 120 km
Explanation:
Speed in downstream = (16 + 4) km/hr = 20 km/hr;
Speed in upstream = (16 – 4) km/hr = 12 km/hr.
Let the distance between P and Q be x km. Then,
x/20 + (x/2)/12 = 11
x/20 + x/24 = 11
⇒ x = 120 km.

Incorrect

Answer – 4) 120 km
Explanation:
Speed in downstream = (16 + 4) km/hr = 20 km/hr;
Speed in upstream = (16 – 4) km/hr = 12 km/hr.
Let the distance between P and Q be x km. Then,
x/20 + (x/2)/12 = 11
x/20 + x/24 = 11
⇒ x = 120 km.

Answer – 2) 30 years
Explanation:
Present total age of the members = 34(5) = 170 years.
Present age of the youngest member = 10 years
Present total age of the remaining four members = 170 – 10 = 160 years
Their average age at the time of the birth of the youngest member = 160 – 40 / 4 = 30

Incorrect

Answer – 2) 30 years
Explanation:
Present total age of the members = 34(5) = 170 years.
Present age of the youngest member = 10 years
Present total age of the remaining four members = 170 – 10 = 160 years
Their average age at the time of the birth of the youngest member = 160 – 40 / 4 = 30

Ramesh spent Rs. 38460 on the health of his family and Rs. 24468 on buying Laptop and remained with 28% of the total amount. What was the total amount?

Correct

Answer – 1) Rs. 87400
Explanation:
Let the total amount = Rs. x
x – 38460 – 24468 = 28x/100
x – 28x/100 = 24468 + 38460
72x/100 = 62928
72x = 62928 * 100
x = 62928 * 100/72
x = 87400

Incorrect

Answer – 1) Rs. 87400
Explanation:
Let the total amount = Rs. x
x – 38460 – 24468 = 28x/100
x – 28x/100 = 24468 + 38460
72x/100 = 62928
72x = 62928 * 100
x = 62928 * 100/72
x = 87400

A supervisor undertake to finish a certain task in 144 days and employed 120 women. After 84 days, he found that he had already done 2/3 of the task. How many women can be discharged so that the task may finish in time?

Correct

Answer – 1) 36
Explanation:
Days remaining 144 – 84 = 60 days
Remaining task = 1 – 2/3 = 1/3
Let required women for working remaining days be ‘x’
So women required = (120 * 84)/2 = (x * 60)/1 => x = 84
women discharge = 120 – 84 = 36

Incorrect

Answer – 1) 36
Explanation:
Days remaining 144 – 84 = 60 days
Remaining task = 1 – 2/3 = 1/3
Let required women for working remaining days be ‘x’
So women required = (120 * 84)/2 = (x * 60)/1 => x = 84
women discharge = 120 – 84 = 36

The sum of the length of two expresses L and M is 770 m. The ratio of the speed of L that of M is 5 : 8. The ratio of time to cross an electric pole by express L to that by M is 4 : 3. Find the difference between the length of the two expresses.

Correct

Answer – 4) 70 m
Explanation:
Ratio of speed of L : M = 5 : 8
Ratio of time of L : M = 4:3
Ratio of length of L : M is = (5*4):(8*3) = 20:24 = 5:6
(5+6)=11=770 m
Required difference =6-5 = 1 = 70 m

Incorrect

Answer – 4) 70 m
Explanation:
Ratio of speed of L : M = 5 : 8
Ratio of time of L : M = 4:3
Ratio of length of L : M is = (5*4):(8*3) = 20:24 = 5:6
(5+6)=11=770 m
Required difference =6-5 = 1 = 70 m
