Q 1 - There are two baskets containing oranges. The first basket of oranges has 1/5 excess to as many oranges in second basket. If second basket has 4 oranges less than first basket, then the number of oranges in the 1st basket is
Number of oranges in second basket = x, in first basket = x + x/5 = 5x/4 Hence, 5x/4 - x = 4X = 4. So option a is correct.
Q 2 - In a leading MNC, there are 51 male employees who are over 150 cm tall. If these constitute three-fourths of the male employees and the total number of male employees is two-thirds of the total number of employees in the class, what is the number of female employees in the class?
Let the number of male employees be x. Then, (3/4) x = 51 or x = 51 × (4/3) = 68.If total number of students is y, then (2/3) y = 68 or y = 68 × (3/2) = 72.Therefore Number of females in the MNC = (72 - 68) = 4.
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?
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 - Jitkumar is a student who studies in a residential college near the Pallikal hills. In a quarterly mathematics exam, Jit got twice as many sums wrong as he got right. If Jit has attempted 48 sums in all then how many did he solve correctly?
Suppose Jit got x sums right and 2x sums wrong. Then, x + 2x = 48 3x = 48 x = 16.
Q 5 - In the annual exam Purusottam Meher has secured a particular number in Mathematics and that number consists of two digits whose sum is 11. If 27 is added to the number, exchange in the places of the digits took place. Find out the number that Purusottam has scored in Mathematics in the annual exam?
Purusottam Meher has scored 47 marks in mathematics, hence, option A is correct.
Q 6 - Average of 13 persons is 36 years. If the age of one person is added the average decreases half a year. What is age of new person?
Total age of 13 persons = 36 × 13 = 468
Total age of 14 persons = 35.5 × 14 = 497 = Age of new person = 497 - 468 = 29 years.

At the closing of an important business conference, ten people those were present in the meeting shake hands with each other once. How many handshakes will there be altogether?

Akshay's one hour work = 1/8. Ahmed's one hour work = 1/10. (Akshay + Ahmed)'s one hour work = 1/8 + 1/10 = 9/40. Both Akshay & Ahmed can finish the work in 40/9 days.
Q 10 - Mr. Das told his son Rinku in a special occasion that, he was of Rinku’s current age when Rinku was born. If Mr Das is 36 now, how old was Rinku five years back?
Let Rinku’s father’s age be x and the Rinku’s age be y.
Then, x – y = y or x = 2y
Now, x = 36. So, 2y = 36 or y = 18.Therefore Rinku’s present age = 18 years. So, Rinku’’s age 5 years ago = 13 years.
