Answer: (a)

Let CP = Rs. x

First SP = 115% of x = $23/20 x$

second CP = 90% of x = ${9x}/10$

second SP = 120% of ${9x}/10 = 120/100 × {9x}/10$

= ${27x}/25$

It is given that

${23x}/20 - {27x}/25 = 28$

${115x –108x}/100$ = 28

$x = {28 × 100}/7$ = Rs. 400

Answer: (c)

Price = Rs. X

SP = Rs. 1.1 x = 0.5 x + 15, So, 0.6 x = 15

So, x = 25

Answer: (d)

Cost price of 30 kg wheat = 30 × 45 = Rs. 1350

Cost price of 30 kg wheat + 25% profit = Selling Price

= 1350 × 1.25 = Rs. 1687.50

40% of 30 kg wheat = 30 × 0.40 = 12 kg

Selling price of 12 kg wheat = 12 × 50 = Rs. 600

Remaining 18 kg wheat's selling price

= 1687.50 – 600 = Rs. 1087.50

∴ Selling price of 1 kg wheat

= $1087.50/18$ = Rs. 60

Answer: (c)
