Q 1 - Rohan was thrice as old as Rakesh three years ago. If difference of their age is 5 years. Find the age of Rohan?
Let the present age of Rohan = x,
Present age of Rakesh = x-5, X = 3(x-3-3)
X = 3x - 18X = 9.
Q 2 - A has $3 more than B, but then B wins on the horses and trebles his money, so that he now has $2 more than the original amount of money that the two boys had between them. How much money did A and B have before B's win?
Let money with A = x. Then, money with B = x + $3. Now, 3x = (x + x + $3) + $2 x = $5.
Therefore total money with A and B = 2x + $3 = $13.
Q 3 - In between two file ends in the rack are six paper weights. If you decide to arrange the six paper weights in every possible combination and moved just one paper weight every minute, how long would it take to you?
Clearly, we can get the answer by taking the factorial.
= 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720.
So total time taken = 720 minutes = 12 hours.
Q 4 - Two friends Ajit and Sujit are working on a project for educational purposes for students between class 6th to 10th. Ajit takes 6 hours to type 32 pages on a computer, while Sujit takes 5 hours to type 40 pages. To type on windows 10, an assignment of 110 pages will be completed by both Ajit and Sujit in how many hours. Two different computers are provided to them.
Only 8 is correct answer, hence, option D is the correct answer.
Q 5 - Suraj is a businessman and for change note purposes, he went to Reserve Bank and he got Rs. 480 with the values consisting of Rs. 10 notes, Rs. 5 notes, and Rs. 1 notes. The number of notes from each category is equal. What is the total number of notes that he has?
Let number of notes of each value be z. Then, 10z + 5z + z = 480. If we will solve it then z = 90. Hence option D is the answer.
Q 6 - There are 75 coins in a bag which contains only 25 paise and 50 paise coins. The value of the coins is 25. Find the numbers of 25 paise coins.
Let the number of 25 paise coins be x. Then number of 50 paise coins will be (75-x).
X × 0.25 + (75-X) × 0.50 = 25
0.25X + 37.50 - 0.50x = 25
0.25x = 12.50
X = 12.50/0.25 = 50
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?
When Rahul was born,
his brother Ranjit’s age = 6 years,
his father Harivansh’s age = ( 6 + 32 ) = 38 years.
His mother Urmila’s age = ( 38 - 3) years = 35 years.
His sister Sharmistha’s age = ( 35 - 25 ) years = 10 years.
Hence, option A.
