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
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
