If the interest on Rs.1650 be less than the interest on Rs.1800 at 4% by Rs.30, find the time for the sums are lent.
Option
a) 2
b) 4
c) 6
d) 7
e) none

• e) none
  
  ((1800-1650)*4*t)/100=30
  600t/100=30
  t=5 yrs
• 9 years agoHelpfull: Yes(3) No(0)
• 1800*4*t-1650*4*t=3000
  600t=3000
  t=5 yrs
• 10 years agoHelpfull: Yes(2) No(4)
• 1800*48*t/100=I
  1650*4*t/100=I-30
  than,(1650*4*t/100)-(1800*4*t/100)=30
  after solving we get t=5 years

• the correct ans . is option (E) None. and the correct ans. is 5 yrs.

• (e)none
  (1800*4*t-1650*4*t)/100=30
  7200t-6600t=30*100
  600t=3000
  t=3000/600
  t=5

• let the time required is t,then
  1650*4*t/100-1800*4*t/100=30
  t=5years

• e)
  none
  1800*4%*t-1650*4%*t=30
  t=5
• 8 years agoHelpfull: Yes(0) No(0)
• ans;E)
  1650-1800=150
  so
  150*4*t/100=30
  t=5
