a) 30%

b) 20%

c) 16%

d) 25%

Shortcut »

Answer: (d)

Gain per cent = ${20 - 16}/16 × 100 = 25%$

Using Rule 8,

Here, x = 20, y = 16

Gain % = $({x - y}/y) × 100$

= ${20 - 16}/16 × 100 = 4/16 × 100 = 25%$

Question : 22 [SSC CGL Prelim 2003]

a) 5%

b) 10%

c) 25%

d) 20%

Shortcut »

Answer: (c)

Let the C.P. of one orange = 1

C.P. of 40 oranges = Rs.40

and S.P. of 40 oranges = Rs.50

Profit = (50 - 40) = Rs.10

Profit % = $10/40 × 100$ = 25%

Using Rule 8,

Here, x = 50, y = 40

Profit % = $({x - y}/y) × 100$

= $({50 - 40}/40) × 100$ = 25%

CP of 4 articles = Rs.4

SP of 4 articles = Rs.5

Profit percent = ${5 - 4}/4 × 100 = 25%$

Using Rule 8,

Here, x = 5, y = 4

Profit % = $({x - y}/y) × 100$

= $({5 - 4}/4) × 100 = 100/4$ = 25%
