Q 1 - In a family, total sum of ages of father and son is 56. After 4 years the age of father is will be 3 times that of his son. The fathers age is.
Options :
Answer : C
Explanation
Let, fathers age = x, age of son would be (56-x), (x+4) = 3(56 - x + 4)
x = 44, Hence, Option C is correct.
Q 2 - Suresh has some grapes when he bought it from a local market near Bhubaneswar. First bunch of grapes has (1/4) as many grapes as the second bunch. If the second bunch has 3 grapes less than the first bunch, then the number of grapes in the first bunch are
Options :
Answer : A
Explanation
Let the number of grapes in the second bunch be a. Then, the number of grapes in the first bunch
= a + (1/4) * a
= (5/4) * a
So,
(5/4) * a - a = 3
5a 4a = 12
a = 12.
Q 3 - Ronit Kumar can cover a distance in 1hr 24min by cycling by covering two third of the distance at four kilometre per hour and rest at a speed of one kilometre more than the previous. Find out the total distance.
Options :
Answer : B
Explanation
Distance = (2/3) S
distance = 1-2/3 S = (1/3)S
21/15 hr = (2/3) S/4 + (1/3) S /5
84 =(14/3)S x 3
S = 6km.
Q 4 - Two trains are running from Jamshedpur and Kanpur towards each other. Train from Jamshedpur takes 2 hours more than that of the train from Kanpur in covering a distance of 30 km. If Jamshedpur train doubles its speed, then it would take 1 hour less than that of Kanpur. Jamshedpur trains speed is?
Options :
Answer : A
Explanation
Let Jamshedpur train's speed be a km/hr. Then, according to the question if we put it in a mathematical formula then (30/a) (30/2a) = 3
6a = 30
a = 5 km/hr.
Q 5 - Sureshs father on his birthday told Suresh that he was of his present age when Suresh was born. If Sureshs father is 36 now, then how old was Suresh five years ago?
Options :
Answer : B
Explanation
Let Sureshs fathers age be x and Sureshs age be y.
Then, x y = y or x = 2y
Now, x = 36. So, 2y = 36 or y = 18.
Therefore Sureshs present age = 18 years. So, Sureshs age 5 years ago = 13 years.
Q 6 - 16 men and 20 boys can do a piece of work in 30 days. In how many days, 15 men and 15 boys will take to finish the work?
Options :
Answer : A
Explanation
16 men = 20 boys
1 man = 5/4 boys
15 men = 75/4 boys
Total no of boys = 75/4 + 15 = 135/4
20 boys = 30 days
135/4 boys = 30 × 20 × 4 /135 = 17 7/9 days
Q 7 - When Raghav Swain was born, his father Harivansh Swain was 32 years older than his brother Ranjit and his mother Urmila was 25 years older than his sister Sharmistha. If Ranjit is 6 years older than Rahul and Mrs Urmila Swain is 3 years younger than Mr. Harivansh, how old was Sharmistha when Rahul was born?
Options :
Answer : A
Explanation
When Rahul was born,
his brother Ranjits age = 6 years,
his father Harivanshs age = ( 6 + 32 ) = 38 years.
His mother Urmilas age = ( 38 - 3) years = 35 years.
His sister Sharmisthas age = ( 35 - 25 ) years = 10 years.
Hence, option A.
Q 8 - P is able to complete a certain task in 6 days and Q can do it within 8 days. P and Q agreed to do the task together for Rs. 4000. R joined them and they finished the task within 3 days. How much is to be paid to R?
Options :
Answer : D
Explanation
$Work \: done \: by \: R \: in \: one \: day \: = \: \frac{1}{3} - \lgroup\frac{1}{6} + \frac{1}{8}\rgroup = \frac{1}{3} - \frac{7}{24} = \frac{1}{24}$
$P's share \: : \: Q's share \: : \: R's Share \: = \: \frac{1}{6} : \frac{1}{8} : \frac{1}{24} = 4 \: : \: 3 \: : \: 1$
$\therefore \: R's \: share \: for \: 3 \: days \:= \: Rs.\lgroup3*\frac{1}{24}*4000\rgroup \: = \: Rs.500.$
