d) 7
e) none
Read Solution (Total 9)
-
- 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 - 9 years agoHelpfull: Yes(1) No(1)
- the correct ans . is option (E) None. and the correct ans. is 5 yrs.
- 9 years agoHelpfull: Yes(0) No(1)
- (e)none
(1800*4*t-1650*4*t)/100=30
7200t-6600t=30*100
600t=3000
t=3000/600
t=5 - 9 years agoHelpfull: Yes(0) No(0)
- let the time required is t,then
1650*4*t/100-1800*4*t/100=30
t=5years - 9 years agoHelpfull: Yes(0) No(0)
- e)
none
1800*4%*t-1650*4%*t=30
t=5 - 9 years agoHelpfull: Yes(0) No(0)
- ans;E)
1650-1800=150
so
150*4*t/100=30
t=5 - 9 years agoHelpfull: Yes(0) No(0)
- c.6
1800*4*1/100-1650*4*1/100
6 - 7 years agoHelpfull: Yes(0) No(0)
