If rs15 are invested today in a saving account ,how much money would there be in the account after 5 years if the compound interest rate is 6 percent

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

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
