Question
A shopkeeper sells a luxury watch at a markup price,
which is (100/3)% above its cost price. Had he purchased the watch for Rs. 300 more and sold it after giving a 10% discount on its previous marked price, he would have neither gained a profit nor incurred a loss. Now, if the shopkeeper aims to earn a 45% profit on the original cost price, find the selling price of the watch.Solution
ATQ, Let the cost price of the luxury watch be Rs. '3a' So, the marked-up price of the luxury watch = '3a' + '3a × (1/3) = Rs.'4a' [(100/3)% = 1/3 ] New cost price of the watch = Rs. (3a + 300) New selling price of the watch = Rs.(90/100) × 4a = Rs. '3.6a' For no profit and no loss, cost price of the watch = selling price of the watch So, 3a + 300 = 3.6a Or, 0.6a = 300 So, a = 500 Required selling price = 1.45 × 3 × 500 = Rs. 2175
√1764 + 35 × 8 + 39 = ?2
18% of 200 - 16% of 150 = ?
25% of 30% of 3/5 of 14500 =?
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
7/3 of 4/5 of 15/56 of ? = 83
What will come in place of the question mark (?) in the following expression?
40% of 150 – ?% of 80 = 25% of 400
555.05 + 55.50 + 5.55 + 5 +0.55 = ?
64.5% of 800 + 36.4% of 1500 = (?)² + 38
What will come in the place of question mark (?) in the given expression?
25% of 1280 + (41 × 4) = ?2
Simplify the following expression:
((32)4 - 1)/33×31× (210+1)
