Question : 26 [SSC CGL Prelim 2004]

If the cost price of 12 pens is equal to the selling price of 8 pens, the gain per cent is :

a) 33$1/3$%

b) 66$2/3$%

c) 50%

d) 25%

Shortcut »

Answer: (c)

Let the CP of each pen be Rs.1.

CP of 8 pens = Rs.8

SP of 8 pens = Rs.12

Gain % = $4/8 ×100$ = 50%

Using Rule 8,

Here, x = 12, y = 8

Profit % = $({x - y}/y) × 100$

= $({12 - 8}/8) × 100$

= $4/8 × 100$ = 50%

Question : 27 [SSC CHSL 2013]

A cloth merchant on selling 33 metres of cloth obtains a profit equal to the selling price of 11 metres of cloth. The profit percent is

a) 40%

b) 22%

c) 11%

d) 50%

Shortcut »

Answer: (d)

S.P. of 33 metres of cloth

= C.P. of 33 metres of cloth +

S.P. of 11 metres of cloth

S.P. of 22 metres of cloth

= C.P. of 33 metres of cloth

Gain per cent = ${33 - 22}/22 × 100$ = 50%

Using Rule 9,

Here, x = 33, y = 11

Profit % = ${y × 100}/{x - y}$

= ${11 × 100}/{33 - 11} = {11 × 100}/22$ = 50%

Question : 28 [SSC CHSL 2011]

The selling price of 12 articles is equal to the cost price of 15 articles. The gain per cent is

a) 6$2/3$%

b) 20%

c) 80%

d) 25%

Shortcut »

Answer: (d)

Gain per cent = ${15 - 12}/12 × 100$ = 25%

Using Rule 8,

Here, x = 15, y = 12

Gain % = $({x - y}/y) × 100$

= ${15 - 12}/12 × 100 = 3/12 × 100$ = 25%

Question : 29 [SSC CGL Tier-1 2011]

Shortcut »

Answer: (c)

Profit percent = ${10 - 8}/8 × 100$ = 25%

Using Rule 8,

Here, x = 10, y = 8

Gain % = $({x - y}/y) × 100$

= ${10 - 8}/8 × 100 = 200/8$ = 25%

Then C.P. of 10 articles = Rs.10

S.P. of 10 articles = Rs.15

Profit = Rs.5

% profit = ${5 × 100}/10$ = 50%

Using Rule 8,

Here, x = 15, y = 10

Profit% = ${x - y}/y × 100$
