- What is the amount invested by A?
Statement I: Total amount received by B after 3 years is Rs.4800 at compound interest.
Statement II: B and A invested their amount at the rate of 10% per annum.
Statement III: A and B invested their amount at simple interest and compound interest respectively and the difference between the interests received by both after 2 years is Rs.1200.Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption E
From statement I,
Let the amount invests by B = x
4800 = x * (1 + R/100)^3
So, Statement I alone is not sufficient to answer the question.
From statement II,
R = 10%
So, Statement II alone is not sufficient to answer the question.
From statement III,
Let the amount invests by A = x
Let amount invests by Bl = y
SI = y * 2 * R/100 = yR/50
CI = x * (1 + R/100)2 – x
CI – SI = 1200
or
SI – CI = 1200
So, Statement III alone is not sufficient to answer the question.
- What is the sum of the ages of person 1 and 2?
Statement I: Ratio of the ages of 1 to 3 is 4: 5 and the ratio of the ages of 1 to 4 is 1: 3.
Statement II: Sum of the ages of 2,3 and 4 is 125 years and 5 years ago the ratio of the ages of 1 to 4 is 3: 11.
Statement III: 4’s age is 200% more than that of 1’s age and the difference between the ages of 1 and 4 is 40 years.Only I and II are sufficientOnly II and III are sufficientEither II alone or I and II together to sufficientAll I, II and III necessary to the answer the questionThe question can’t be answered even with all I, II and IIIOption A
From statement I,
p1/p3 = 4/5
p1/p4 = 1/3
So, Statement I alone is not sufficient to answer the question
From Statement II,
p2 + p3 + p4 = 125
(p1 – 5)/(p4 – 5) = 3/11
So, Statement II alone is not sufficient to answer the question
From statement III,
p4 = 300/100 * p1
p4: p1 = 3: 1
2x = 40
x = 20
p1= 20 years
p4 = 3 * 20 = 60 years
So, Statement III alone is not sufficient to answer the question
From statement I and II,
p1 and p4’s present age be x and 3x respectively
(p1 – 5)/(p4 – 5) = 3/11
(x – 5)/(3x – 5) = 3/11
= > 11x – 55 = 9x – 15
= > 2x = 40
= > x = 20
Present age of p1 and p4 is 20 and 60 years respectively
p3’s present age = 20/4 * 5 = 25 years
p2’s present age = 125 – (25 + 60) = 125 – 85 = 40 years
Sum of the ages of p1 and p2 = (20 + 40) = 60 years
Hence, statement I and II alone is sufficient to answer the given question.

p2 = 2x
p3= (x + 1000)
p4 = 3x
So, Statement I alone is not sufficient to answer the question
From Statement II,
p3’s share = Rs.4000
So, Statement I alone is not sufficient to answer the question
From statement III,
Profit ratio of p3/p4 = 2/3
So, Statement III alone is not sufficient to answer the question
From I, II and III
Profit ratio of p1, p2, p3 and p4 = x * 12: 2x * 12: (x + 1000) * 6: 3x * 6
=12x: 24x: (6x + 6000): 18x
(6x + 6000)/18x = 2/3
6x + 6000 = 12x
x = 1000
Profit ratio = 12000: 24000: 12000: 18000
= 2: 4: 2: 3
p2’s profit share = 4/2 * 4000 = 8000
All the statements are necessary to answer the question.
