Question
Mr. X invested Rs. 900 in two schemes, A and B in the
ratio of 7:3, respectively. Scheme A and B are offering simple interest at rate of 14% per annum and 18% per annum. Find the total interest obtained from both schemes after 2 years.Solution
Amount invested in scheme A = (7/10) × 900 = Rs. 630 Amount invested in scheme B = (3/10) × 900 = Rs. 270 Interest earned from scheme A = 630 × 14% × 2 = Rs. 176.4 Interest earned from scheme B = 270 × 18% × 2 = Rs. 97.2 Therefore, required total interest = 176.4 + 97.2 = Rs. 273.60
√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)
