Question
The simple interest on a certain sum is one-eighth of
the sum when the number of years is equal to half of the rate percentage per annum. Find the simple interest (in. Rs) on rs 15,000 at the same rate as simple interest for 8 years.Solution
given - SI= P × 1/8, T= R×1/2 SI=PRT/100 P/8=P×R×R/200 R² =200/8=25 R² =25 R=5% now find the simple interest, P=1500 R=5% T=8years = (15000×5×8)/100 = 6000rs
What will come in the place of question mark (?) in the given expression?
?% of 2480 + 15 × 34 = 1440
(82 + 62 ) × 1.25 + 20% of 145 = ? – 40% of 65Â
Evaluate: (768÷16)×(125÷25)−(81÷9)×12
What will come in place of (?) in the given expression.
40% of (120 + 80) + 25% of 160 = ?What value should come in the place of (?) in the following questions?
(3√1728 * 25) ÷ 3 * ? = 250 + 50* 3
What will come in the place of question mark (?) in the given expression?
65% of 900 - 45% of 600 = ? X 3Â
- What will come in the place of question mark (?) in the given expression?
?² = 28% of 35% of 4500 Simplify the expression:
(9x² - 25) / (3x + 5)
[{(3 × 54 × 21)/63} + 6] / 6 = √?Â
3.2% of 500 × 2.4% of ? = 288
