(b) 20%

(c) 10%

(d) 8%

The correct answers to the above question in:

Answer: (c)

Marked price of tape recorder

= ${1500 × 120}/100$ = Rs.1800

Gain = ${1500 × 8}/100$ = Rs.120

Discount = 1800 - (1500 + 120) = Rs.180

Let Discount per cent = x%, then

${1800 × x}/100$ = 180 ⇒ x = 10%

Method 2 :

If the discount be x%, then

$20 - x - {20x}/100$ = 8

$20 - {6x}/5 = 8$

${6x}/5$ = 20 - 8 = 12

$ x = {12 × 5}/6$ = 10%

b) 10% loss

c) 10% gain

S.P. of each book = ${75 × 70}/100$ = Rs.52.50

Total S.P. = 1600 × 52.50 = Rs.84000

Gain = 84000 - 70000 = Rs.14000

Gain% = $14000/70000 × 100$ = 20%

After corresponding increases

${x × 120}/100 - 200 = 2(x - 200)$

${6x}/5 - 200 = 2x - 400$

6x - 1000 = 10x - 2000

4x = 1000 ⇒ x = Rs.250

Answer: (b)

Let the CP be Rs.100. Then, SP = Rs.120.
