9*8*7*6/4*3*2*1= 126 combinations
The answer is 75.
Let's look at your problem shall we:
Odd number: It should end with the numbers 1,3,5,7, and 9.
The number is less than 100: It should be from the number 1-99
Sum of digits: 12
Multiple of 15: 15, 30, 45, 60, 75, and 90.
We can rule out 30, 60, and 90 because they are even.
1+5 = 6; 4+5=9; 7+5 = 12
You are left with 75.
Answer:
so the answer is RS 20200
Step-by-step explanation:
simple formula for calculation ( as for compound interest you have to invest initially)
starting total investment Pₓ = Rs 150000
Interest rate r= 6 % = 0.06
compounds in years total K = (12 months)
for how many year you want to invest Pₙ = 5
formula
Pₙ = Px (1 + r/k) ⁿ ˣ ¹²
P₅ = 150000 (1 + .06/12) ¹² ˣ⁵
= 150000 (1.005) ⁶⁰
= 150000 x 1.348
= Rs 202200
