d) In 20 Litres of Water it is 35 % Full,

  It Full 1 % in 20 Litres/35=4/7

  Then In 65 % ,

The Required litres of water is 65 ×4/7

                                           = 260/7=37.14 Litres Of Water.

e) As Mr. Sanjay Deposited 15,000 to Bank i.e Principal = 15,000

As His Present age of his daughter is 5 and he wants 21,000 as amount at thirteen year old,

So, Time=13-5=8 Years

Time=8 Years and Amount is 21,000

As Simple Interest,

Let Interest is x

So, x=Principal×Time ×Rate of Interest/100

x=15,000×8×Rate/100=120000×Rate/100

⇒x=1200×Rate of interest

⇒Amount= Principal + Interest

⇒21,000=15,000+Interest

⇒21,000-15,000=Interest

⇒6,000=Interest

⇒Rate of interest=6,000/3=2000 Per Annum
