 Correct Answers: Wrong Answers: Unattempted:

### Question 1

A sum of Rs. 6600 is to be divided among three partners, P, Q and R, in the ratio 6 : 2 : 3. How much does Q get?

A

Rs. 1200.

B

Rs. 1202.

C

Rs. 1198.

D

Rs. 1204.

Soln.
Ans: a

The share of Q is in the ratio like this: \$2/{6 + 2 + 3} × 6600\$ = Rs. 1200.

### Question 2

If a : b is 17 : 9, then what is (4a - 3b) : (7a - 8b)?

A

\${41/47}\$.

B

\$1{21/23}\$.

C

\$2{37/49}\$.

D

\$3{5/7}\$.

Soln.
Ans: a

Simply substitute the values to get (4a - 3b) : (7a - 8b) as (4 × 17 - 3 × 9) : (7 × 17 - 8 × 9) = \$41/47\$ = \${41/47}\$.

### Question 3

Two numbers A and B are in ratio 15 : 11. If they are both increased by 40%, what will be the new ratio of A : B?

A

\$1{4/11}\$.

B

\$2{3/5}\$.

C

\${4/13}\$.

D

\$3{9/13}\$.

Soln.
Ans: a

New A will scale to \$140/100\$ × 15, and B to \$140/100\$ × 11. New ratio is \${140 × 15}/{140 × 11}\$ = \${15/11}\$, which is same as: \$1{4/11}\$.

### Question 4

The ratio of shares of three friends in Rs. 2400 are in an A.P.(arithmtic progression). What is the share of the friend who is neither the richest, nor the poorest?

A

Rs. 800.

B

Rs. 804.

C

Rs. 796.

D

Rs. 808.

Soln.
Ans: a

Let the shares be in the ratio a - d : a : a + d. The value of the middle item is \$a/{(a - d) + a + (a + d)}\$ × 2400 = \$a/{3a}\$ × 2400 = \$2400/3\$ = Rs. 800.

### Question 5

If X is 50% more than Z, and Y is 60% more than Z, what is the ratio of X to Y?

A

\${15/16}\$.

B

\$2{1/15}\$.

C

\$2{11/18}\$.

D

\$3{1/2}\$.

Soln.
Ans: a

Clearly, X = \$(100 + 50)/100\$ × Z, and Y = \$(100 + 60)/100\$ × Z, which gives X : Y as \$(100 + 50)/(100 + 60)\$ = \$150/160\$ = \${15/16}\$
