Question 1 of 10

1. Question

1 points

Category: Quantitative Aptitude

Find the sum of the last three positive consecutive odd numbers
I. The average of four consecutive odd numbers is 36
II. The difference between the highest positive odd number and the lowest positive odd number is 6

Correct

Answer – 1) The data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
Explanation:
From I
Let the first odd number X
Then (X+X+2+X+4+X+6)/4=36
X=33
Four consecutive number =33,35,37,39
The sum of the last three consecutive numbers = 35 + 37 + 39 = 111

Incorrect

Explanation:
From I
Let the first odd number X
Then (X+X+2+X+4+X+6)/4=36
X=33
Four consecutive number =33,35,37,39
The sum of the last three consecutive numbers = 35 + 37 + 39 = 111

Answer – 5) X = Y or relation cannot be established
Explanation:
3x² + 10x + 8 = 0
3x² + 6x + 4x + 8 = 0
x = -1.33, -2
3y² + 11y + 6 = 0
3y² + 9y + 2y + 6 = 0
y = -0.66, -3

Incorrect

Category: Quantitative Aptitude

Mr. Suresh invested Rs X in Simple Interest(SI) at a rate of interest of 15% for 5 years then he invested X+600 at Compound Interest(CI) at 10% rate for 2 years. The total interest obtained is Rs 5310. Find the amount (in Rs) invested in SI by Suresh.

Directions.Q(6-10) Study the following table carefully and answer the questions given below :

If the ratio of the rate of simple interest on the amount invested by T to the rate of simple interest on the amount invested by S is 2 : 5, then what will be the invested amount by S that earns an simple interest of Rs 12000

Correct

Answer – 3) 20000
Explanation:
Rate of interest for S = 5 *6/2=15%
12000*100=P*4*15
P=20000

Incorrect

Answer – 3) 20000
Explanation:
Rate of interest for S = 5 *6/2=15%
12000*100=P*4*15
P=20000

Category: Quantitative Aptitude

Directions.Q(6-10) Study the following table carefully and answer the questions given below :

If R invests his money, which is compounded annually for 3 years at the rate of 4 % then what is the difference between the amount earned by R after 3 years and that after 2 years?

Directions.Q(6-10) Study the following table carefully and answer the questions given below :

The ratio of the principal of Q to that of R is 5 : 4. If the rate of simple interest of Q is 25% more than the rate of interest applied for R, then calculate the simple interest earned by Q?

Correct

Answer – 5) 2500
Explanation:
Principal of Q =5/4 * 10000=Rs 12500
Rate of interest will be = 4 * 125/100 = 5%
Simple Interest earned by Q,
I *100=12500*4*5 = Rs 2500

Incorrect

Answer – 5) 2500
Explanation:
Principal of Q =5/4 * 10000=Rs 12500
Rate of interest will be = 4 * 125/100 = 5%
Simple Interest earned by Q,
I *100=12500*4*5 = Rs 2500

Question 9 of 10

9. Question

Category: Quantitative Aptitude

Directions.Q(6-10) Study the following table carefully and answer the questions given below :

If P invests 20% more money than that invested by T, what will be the amount received by P after 3 years if he invests the amount at the rate of 5% compounded annually

Correct

Answer – 3) 13891.5
Explanation:
Money invested by T = Rs 10000
Money invested by P = 10000 * 120/100 = 12000
(12000 * 105 * 105 * 105)/(100 * 100 * 100)
=13891.5

Incorrect

Answer – 3) 13891.5
Explanation:
Money invested by T = Rs 10000
Money invested by P = 10000 * 120/100 = 12000
(12000 * 105 * 105 * 105)/(100 * 100 * 100)
=13891.5

Question 10 of 10

10. Question

1 points

Category: Quantitative Aptitude

Directions.Q(6-10) Study the following table carefully and answer the questions given below :

If the amount received by S is equal to 4 times the interest by him then what will be that rate of interest if calculated at simple interest ?

Correct

Answer – 4) 25/3%
Explanation:
Amount received by S =32000
If the amount is 4X and interest is X then principal is 3x
4X = 32000
X = 8000
Principal = 24000
8000 *100 = 24000 * 4 * R
R= 25/3%

Incorrect

Answer – 4) 25/3%
Explanation:
Amount received by S =32000
If the amount is 4X and interest is X then principal is 3x
4X = 32000
X = 8000
Principal = 24000
8000 *100 = 24000 * 4 * R
R= 25/3%
