Q:

A and B enter into partnership. A supplies whole of the capital amounting to Rs. 45000 with the condition that the profits to be equally divided and that B pays A interest on half of the capital at 10% per annum, but receives Rs. 120 per month for carrying on the concern.Find their total yearly profit when B's income is one half of A's income.

Answer

Let the total profit be Rs. x

Amount paid to B as salary = (120 x 12)

= Rs.1440

Share of each = $\inline (\frac{x-1440}{2})$

Interest paid by B = $\inline \frac{22500\times 10}{100}=Rs.2250$

Total money received by A = $\inline \frac{x-1440}{2}+2250$

= Rs. $\inline (\frac{x+3060}{2})$

Total money received by B

$\inline [(\frac{x-1440}{2})+1440-2250]= (\frac{x-3060}{2})$

$\inline \Rightarrow \frac{1}{2}-(\frac{x+3060}{2})-(\frac{x-3060}{2})$

$\inline \Rightarrow x=9180$

Q:

The ratio of water and alcohol in two different containers is 2:3 and 4:5. In what ratio we are required to mix the mixtures of two containers in order to get the new mixture in which the ratio of alcohol and water be 7:5?

A) 7:3	B) 5:3
C) 8:5	D) 2:7

Answer & Explanation Answer: B) 5:3

Explanation:

$W 1 : A 1 W 2 : A 2 . . . . . W N : A N$

2 : 3 4 : 5 5 : 7

$\frac{W 1}{W 1 + A 1} = \frac{2}{5} \frac{W 2}{W 2 + A 2} = \frac{4}{9} \frac{W N}{W N + A N} = \frac{5}{12}$

= 72/180

= 80/180

= 75/180

=> 5 : 3

Therefore, the ratio is 5: 3
