a. 36
b. 88
c. 114
d. 124
Read Solution (Total 9)
-
- no of 1 kg boxes = x;
no of 2 kg boxes = y;
x+y=150;
Total weight = x*1 + y*2
x+2y=264;
y=114

- option verification: c
114*2+36*1=264
114+36 gives 150 pakages - 10 years agoHelpfull: Yes(1) No(1)
- answer c,
(114*2)+(150-114)=264 - 10 years agoHelpfull: Yes(1) No(1)
- 2*x + (150 - x) = 264
=> x=114

- Ans. is Option C
Total no. of boxes=150
No. of 1 kg boxes=x;
No. of 2 kg boxes= 150-x;
(x*1)+(150-x*2)=264
-x=-36 i.e x=36
150-x
150-36=114 - 9 years agoHelpfull: Yes(1) No(0)
- let 1kg box be x and 2kg y
x+y=150
x*2y=264
on solving,x=114 any y=36
hence 36 - 10 years agoHelpfull: Yes(0) No(0)
- Correct Answer is c.114.
Let number of 1kg be x and number of 2kg be y. Then x+y=150 and x+2y=264.
Solving for y we get y=264-150=114. Hence the option C. - 10 years agoHelpfull: Yes(0) No(0)
- 114.
if u take x packages of 1kg bags then left over i.e. 150-x will be 2 kg packages.
x*1 + (150-x)*2=264
=>x=36
so 150-36=114 ---2 kg packages - 6 years agoHelpfull: Yes(0) No(0)
- X+y=150
x+2y=264
Y=114 - 6 years agoHelpfull: Yes(0) No(0)
