Question
Compound interest on a certain sum of money for 2 years
is Rs.2860 while the simple interest on the same sum for the same time period is Rs.2600. Find the rate of interest.Solution
SI for 1 year = 2600/2 = Rs.1300 Difference between CI and SI for 2 years = Rs.(2860 β 2600) = Rs.260 Required rate = (260/1300) x 100 = 20%
(350/?) = 23 + 33
(630 Γ· 35) Γ 2 + 144 = ? Γ 2
?/4 ÷ 9/? = 15% of 800 + `1(2/3)` × `1(1/5)` × 1/2
236.23-653.23+696.23=?
72 Γ 2 = ? + 104 β 14
36895 - 4256 - 2233 = ?Β
What will come in the place of question mark (?) in the given expression?
3.6 X 15 + 4.5 X 12 = 40% of (? - 50)? = 15% of 2400 + 140% of 4200 β 12 3Β
β121 + β961β β289 =?2
