Question
A trader buys 500 shares of a company at ₹240 each. He
pays a 0.5% brokerage on the purchase. After two months, he sells all shares at ₹260 each, paying 0.5% brokerage on the sale. Find his net profit and percentage return on the total investment.Solution
ATQ,
Buying cost: Price per share = ₹240 Brokerage = 0.5% of 240 = 1.2 Total cost per share = 240 + 1.2 = 241.2 Total investment = 500 × 241.2 = ₹120,600 Selling proceeds: Selling price per share = ₹260 Brokerage = 0.5% of 260 = 1.3 Net sale price per share = 260 − 1.3 = 258.7 Total sale proceeds = 500 × 258.7 = ₹129,350 Profit: Profit = 129,350 − 120,600 = ₹8,750 Percentage return = (8750 / 120,600) × 100 = 7.25% Hence, Net Profit = ₹8,750 and Percentage Return = 7.25%
82% of 400 + √(?) = 130% of 600 - 85% of 400
34 × 2.5 + 6.4 × 1.5 – 4.8 × 1.2 =?

1428 ÷ 17 = ? % of 120
(23.95)2 – (25.006)2 + (8.0099)2 – (7.07)2 = ? - (14.990)2
What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
Calculate the simplified value of the given expression:

If (4 × 169 – 312 ÷ 12) ÷ 22 = √1296 – x, then determine the value of ‘x’.
(5/8 + 7/12) x 168 = ? + 93 - 25
