Answer: (a)

Let labelled price of T.V. be Rs. x

Price after 20% discount, $x – 20/100 x$ = 0.8x

Price after 30% discount, $x – 30/100 x$ = 0.7x

According to question

0.8x – 0.7x = 800

x = 800 × 10 = 8000

Answer: (c)

Let the actual C.P. of cloth = Rs.1

Then the effective C.P. = $100/110 = 10/11$

(Since he purchases 110 articles by paying Rs. 100)

Again S.P. = $100/90 = 10/9$

(Since he sells only 90 articles charging the CP of 100 articles).

∴ Gain% = $\text"S.P - C.P"/\text"C.P" × 100 = {10/9 - 10/11}/{10/11} × 100$

= $20/99 × 11/10 × 100 = 200/9 = 22{2}/9$ %

∴ Option (c) is correct.

Answer: (c)

Cost price per article = 311

Selling price per article = $9954/21$ = 474

Profit per article = ${474 - 311}/311$ × 100 = 52%

Answer: (b)

RM + MC = Total cost

Total cost + Profit = Sale price

70 + 30 = 100, 100 + 10 = 110

84 + 42 = 126, 126 + 72 = 198 (110 + 80% = 198)

Therefore profit % = $72/126 × 100$ = 57.14%

Answer: (c)

SP of 1 kg of mixture = Rs. 66 per kg

Profit = 10%

CP of 1 kg of mxiture = Rs. $(100/110 × 66)$ = Rs. 60

By the rule of alligation we have

Cost of 1 kg of rise of Ist kind Cost of 1 kg of rice of IInd kind

Reqduired ratio = 10 : 20 = 1 : 2
