Q 3 - A snail moves up 30 cm when each hour is started and stops for a while when it slips back 20 cm before it again starts climbing in the beginning of the next hour. If it begins its ascent at 8.00 a.m., at what time will it first touch a flower at 120 cm from the ground?
Options :
Answer : B
Explanation
Let the ascent of the snail in 1 hour = ( 30 - 20 ) = 10 cm.
So, the snail ascends 90 cm in 9 hours i.e., 5 p.m.
Clearly, in the next 1 hour i.e., till 6 p.m.
The snail ascends remaining 30 cm to touch the flower.
Q 4 - A can do ¼ of a work in 10 days, B can do 40% of work in 40 days and C can do 1/3 of work in 13 days. Who will complete the work first?
Options :
Answer : C
Explanation
Whole work will be done by A in 10 × 4 = 40 days. Whole work will be done by B in (40 × 100/40) = 100 days. Whole work will be done by C in (13 × 3) = 39 days. Therefore, C will complete the work first.
Q 5 - Suresh’s father on his birthday told Suresh that he was of his present age when Suresh was born. If Suresh’s father is 36 now, then how old was Suresh five years ago?
Options :
Answer : B
Explanation
Let Suresh’s father’s age be x and Suresh’s age be y.
Then, x – y = y or x = 2y
Now, x = 36. So, 2y = 36 or y = 18.
Therefore Suresh’s present age = 18 years. So, Suresh’s age 5 years ago = 13 years.
Q 6 - In ABC suppliers, a leading private company situated at Tripura, 16 men can complete a loading and supplying job in 10 days. How many extra men are required to complete that work within 8 days?

Q 7 - July 28 is my birthday and I usually distribute rasagollas to my friends on that eve. I have a few rasagollas to be distributed. If I keep 2, 3 or 4 in pack, I am left with one Rasagolla. If I keep 5 in a pack, I am left with none. What is the minimum number of rasagollas I have to pack and distribute?
Options :
Answer : A
Explanation
By packing 5 rasagollas in a pack, we would be left with no extra ones.
So, the total number of Rasagollaas is obviously divisible by 5.
This eliminates the option C.
By packing 2,3, or 4 Rasagollas in a pack, we are left with 1 rasogolla
So, (the number of Rasagollas -1) must be divisible by 2,3, and 4
In case of option A, (25 - 1 = 24) is divisible by 2, 3, and 4.
In case of option B, (35 - 1 = 34) is divisible by 2 but is not divisible by 3 and 4. So, this eliminates option B.
In case of option D, (65 - 1 = 64) is divisible by both 2 and 4, but, is not divisible by 3. This eliminates option D also.
So, the only eligible option left with us is 25.
So, option A would be the answer.
Q 8 - Mahesh Sharma is now three times as old as his son Bipul Sharma. Five years back, Mahesh was four times as old as Bipul. The age of the Bipul(in years) is

Five years ago, Mahesh’s age = (3x - 5) years and Bipul’s age will be 5.
