QUESTION: 2

Q(1 – 10) Each of the questions below consists of a question and two/three statements given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –

Total amount of Rs. 50600 was distributed among A, B and C. How much does each get?
I. A gets 2/9 of what the other two together get.

QUESTION: 12

Q(11 – 20) Each of the questions below consists of a question and three statements given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –

What are the ages of Lia and Mia?

Solution:

I –> Mangesh – Lia = 5
Mia – Mangesh = 7
=> Mia –Lia = 12
II –> Lia : Mia = 15:19
4 ratio =12
1 ratio = 3
Therefore, Lia = 45 & Mia = 57
III –> Mangesh + Lia = 95
=> Lia’s age = (95-5)/2 = 45
Therefore , Mia’s age = 45=12 = 57

QUESTION: 14

Q(11 – 20) Each of the questions below consists of a question and three statements given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –

What are the marks obtained by Sreya and Kia(assuming Sreya scored less than Kia)?
I. The sum of their marks form 70% of the total score.

Solution:

IV –> Sreya’s mark = sqrt(68121) * 2* 5/3 *5/6 = 725.
II –> S: K = 29:41
29 ratio = 725 => 1 ratio = 25
Therefore , Kia’s mark = 41*25 = 1025.
III —>( S+K) : (K-S) = 35:6 => S:K = 29:41

QUESTION: 15

QUESTION: 16

Q(11 – 20) Each of the questions below consists of a question and three statements given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –

A and B together completed a work in 6 days. They got Rs. 1350 as remuneration. What would be the ratio in which the 1350 Rs would be split if C worked along with A and B?
I. Ratio of no: of days taken by A & C is 5:9
II. Ratio of efficiency of A & B = 3:2
III. C is the least efficient of all

Solution:

Days 5x 9x
efficiency 3y 2y
Total work / (3y+2y) = 6 => 30y = TW
5 x —->3y
9x —–>?
=> Efficiency of C = 5/3 y
Therefore ratio = 3:2:5/3 = 9:6:5

QUESTION: 20

Q(11 – 20) Each of the questions below consists of a question and three statements given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –

 What is the area of the plot which is in the shape of a regular polygon?
I. Perimeter of the plot is 1036m
II. Radius of the largest circle that can be inscribed in the plot is 129.5m
III. Diameter of the largest circle that can be inscribed in the plot is equal to the length one side of the plot.

Solution:

From III, it is clear that the plot is square, as the side of the regular polygon shaped plot is equal to the diameter of the biggest circle that can be inscribed in it.
From I, 4a = 1036m
=> a = 259m
=> area = 259*259 = 67081sq.m
Or,
From II, radius of circle = 129.5m
Therefore, diameter = a = 129.5*2 = 259m
=> area = 67081 sq.m
