Answer: (c)

Let A paid = Rs. x

125 % of 120% of x = 225

⇒ $125/100 × 120/100 × x = 225$

⇒ $x = {225 × 100 × 100}/{125 × 120}$ = Rs. 150

Answer: (c)

Rs. 150 + $20/100 × 150$ = Rs.180

S.P = Rs.180

Answer: (a)

By the rule of fraction:

He purchased 15$({100 - 9}/100)$ for a rupee.

Now to gain 5%, he must sell 15$(91/100)(100/105) = 13$ for a rupee

Answer: (a)

x + y + ${xy}/100$

= +20 - 20 - ${20 × 20}/100$ = -4%

Total selling price of a refrigerator and a camera

= 12000 + 12000 = Rs. 24000

Now, loss is 4%

CP × $96/100$ = 24000

CP = Rs. 25000

Loss amount = (25000 - 24000) = Rs. 1000

Answer: (a)

Let C.P.= Rs. $x/\text"dozen" = Rs.{100x}/12$ per hundred and SP ${8x}/\text"hundred"$

% profit = ${8x - {100x}/12}/{{100x}/12} × 100$

= ${96x - 100x}/{12 × 100x} × 100 × 12$

Rs. = - 4%
