A. 9
B. 15
C. 18
D. 21

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Let the greater number is = x

and the smaller number is = y

According to the question,

x - y = 3/7 (x + y)

or, 7x - 7y = 3x + 3y

or, 7x - 3y = 3y + 7y

or, 4x = 10y

or, 4x = 10*6 [As the smaller number is 6]

or, 4x = 60

or, x = 15

Ans: The greater number is 15

3328 . The savings of an employee equals income minus expenditure. If their incomes ratio is 1 : 2 : 3 and their expenses ratio is 3 : 2 : 1, then what is the order of the employees A, B and C in the increasing order of the size of their savings?

A. A>B>C
B. A>C>B
C. B>A>C
D. C>B>A

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let's denote the income of employees A, B, and C as IA, IB, and IC, respectively. Similarly, let's denote their expenses as EA, EB, and EC.

According to the given ratios: Income ratio = 1:2:3 Expenses ratio = 3:2:1

Now, let's calculate the savings for each employee:

Savings of A = IA - EA Savings of B = IB - EB Savings of C = IC - EC

Now, let's calculate the savings for each employee using the given ratios:

Income ratio = 1:2:3 Expenses ratio = 3:2:1

Let's assume that the common multiplier for both ratios is "x" (where x is a positive number).

So, the income for A, B, and C would be: IA = 1x IB = 2x IC = 3x

And the expenses for A, B, and C would be: EA = 3x EB = 2x EC = 1x

Now, let's calculate the savings for each employee:

Savings of A = IA - EA = (1x - 3x) = -2x Savings of B = IB - EB = (2x - 2x) = 0 Savings of C = IC - EC = (3x - 1x) = 2x

Now, let's order the employees in increasing order of the size of their savings:

Savings of A = -2x
Savings of B = 0
Savings of C = 2x

So, the correct order of employees in increasing order of the size of their savings is A > B > C.

The correct answer is A > B > C.

3329 . The second and third term of a geometric series are 9 and 3 respectivelt ,. The 6 th term of the series is-

B. 1/3
C. 1
D. 1/9

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

To find the 6th term of the geometric series, we can first find the common ratio (r) of the series. The common ratio can be found by dividing the third term by the second term:

r = 3rd term / 2nd term = 3 / 9 = 1/3

Now that we have the common ratio, we can use it to find the 6th term (T6) using the formula for the nth term of a geometric series:

Tn = a * r^(n-1)

Where: Tn = nth term a = first term r = common ratio

In this case, the first term (a) is not given, but we can find it using the second term and the common ratio:

a = 2nd term / r = 9 / (1/3) = 9 * 3 = 27

Now that we have the first term, we can find the 6th term:

T6 = 27 * (1/3)^(6-1) = 27 * (1/3)^5 = 27 * (1/243) = 1/9

So, the 6th term of the geometric series is 1/9.

Explanation:

The sum of angles of a triangle = 180∘.

Given: One angle is 90∘(since it is a right angled triangle ) and another angle is 30∘

Hence, 90∘+30∘+Third angle=180∘

⇒120∘+Third angle=180∘

∴Third angle=180∘−120∘=60
