Correct Answer: 5 litres

Solution : Let the quantity of milk and water in the mixture be $5x$ and $3x$.
Quantity of water added $=$ 7 litres
The new quantity of water in the mixture $= 3x+7$ litres
According to the question,
$\frac{(5x)}{(3x+7)} = \frac{1}{2}$
⇒ $10x = 3x+7$
⇒

Correct Answer: Rs. 265

Solution : Let per day income of a boy, woman, and man be $x, x+10,$ and $x+20,$ respectively.
According to the question,
$\frac{\text{Total income of (7 Men + 11 Women + 2 Boys)}}{20} = 257.50$
Putting the values, we get:
$7(x+20)+11(x+10)+2x = 257.50×20$
$⇒7x+140+11x+110+2x = 5150$

Correct Answer: MXJY

Correct Answer: $\pm 2$

Solution : Given: $(x+\frac{1}{x}):(x-\frac{1}{x})=5:3$
By using Componendo and Dividendo rule, $a:b = c:d ⇒ \frac{a+b}{a–b}=\frac{c+d}{c–d}$,
where $a=x,b=\frac{1}{x},c=5,$ and $d=3$
By putting the given value of a, b, c, d in the formula, we get:
$\frac{x+\frac{1}{x}+x-\frac{1}{x}}{x+\frac{1}{x}-x+\frac{1}{x}}=\frac{5+3}{5-3}$
⇒ $\frac{2x}{\frac{2}{x}}=\frac{8}{2}$
⇒ $x^{2}=4$
$\therefore x=\pm 2$
Hence, the correct answer

Correct Answer: 10

Solution : Given:
625 : 5 :: 2560 : 8 :: 5000 : ?

Like, 625 : 5; 625 ÷ 5 = 125; 125 = 5³
And, 2560 : 8; 2560 ÷ 5 = 512; 512 = 8³
Similarly, 5000 : ?; 5000 ÷ 5
