In how many years will a sum of money becomes triple at 10% per annumm
option
a)10
b)15
c)30
d)none

• R=10%,S.I=3P-P=2P
  T=100*S.I/PR=100*2P/P*10=20
  so ans:d)none

• SI= Amount principle - principle i.e 3x-x (let x be the principle)
  so, SI= P*R*T/100
  2x=x*10/100*T
  => t=20 years
  hence option d

• when sum of money become n time then...
  100(n-1)=RT
  so 100(3-1)=10T
  T=20 yr
  option d

• 30????????

• let us suppose we take 100 as an amount
  (P*R*T)/100 = (100*10*30)/100=300
  which is triple of 100
  hence d is the ri8 answer

• ans :20
  because if p is the principal amount the then after 20 years with simple interest it becomes 2p. so ans is (d) i.e none.

• let sum of money=100
  its become triple= 300
  so simple interest=300-100=200
  formula: s.i=p*r*t/100
  200=100*10*t/100
  t=200/10=20year
