Question
Rs. 8000 was lent in two parts, first part at 5 % p.a.
and the remaining at 4% p.a. If the total simple interest from both the parts in 4 years was Rs. 1360, then what will be the ratio of amount of the 2 different parts?Solution
ATQ, Let first part of money be A rupees then second part will (8000-A) rupees. Simple interest = Principal × Rate of interest × Number of years/100 Now according to question- A×5×4/100 + (8000-A) ×4×4/100 = 1360 20A + 16× (8000-A) = 136000 4A = 136000 – 128000 A = 2000 Second part = 8000-2000 = 6000 Ratio = 2000/6000 = 1:3
41.66% of 888 + 66.66% of 1176 = ?2 - 4√ 16 Â
Evaluate: 320 − {18 + 4 × (21 − 9)}
Simplify: 72 ÷ 6 × 3 − 8 + 4
118 × 6 + 13 + 83 = ?
Simplify the following expression:
  (400 +175) ² - (400 – 175) ² / (400 × 175)
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
(75 + 0.25 × 10) × 4 = ?2 - 14
26% of 650 + 15% of 660 – 26% of 450 = ?
115% of 40 + 3 × 4 = ? × 11 – 8
