Find the probability if a two digit number multiplied by 3 but not 5

A1/12

B3/16

C2/5

D4/15

ENone of above

| | Important Formulas | Topic: | Asked In |

Explanation:

Total two digit numbers are 90 i.e. from 10 to 99
numbers multiple of 3 are 12, 15, 18, ......., 99 so 12+(n-1)3=99, n=30
numbers multiple of 3 & 5 both are 15,30,45,60,75,90 total 6
So two digit numbers multiple of 3 but not of 5 are 30-6=24
Probability=24/90=4/15

The difference between the compound and simple interest on a certain sum for 2 years at the rate of 8% per annum is Rs.80. What is the sum?

A12,500

B13,250

C14,270

| | Important Formulas | Topic: | Asked In |

Explanation:

Since we know that SI and CI are same for first year. Difference is due to the SI of 1st year is treated as PRINCIPLE of 2nd year in CI.
So 1st we calculate the amount which treated as P in CI
P = 100*SI/R*T = 100*80/8*1 = 1000
This amount is also the SI for 1 year.
So,
SI = 1000
T = 1 Year
R = 8%
P = 100*1000/8*1 = 12500
