If a lemon and apple together costs Rs. 12, a tomato and lemon cost Rs.4 and an apple cost of Rs.8 more than a tomato or a lemon, then which of the following can be the price of lemon?
Option
a) Rs.2
b) Rs.4
c) Rs.1
d) Rs.3
Read Solution (Total 12)
-
- As given,
L+A=12 .....(1)
L+T=4 .......(2)
A=8+L
or L-A=-8 ......(3)
A=8+T .......(4)
Simply adding eq. 1 and 3
We get..
2L=4
So, L=2

- l+a=12;;;_1eq t+l=4;_2eq
a=8+l;;;_3eq
from 1 and 3
l=2 - 10 years agoHelpfull: Yes(7) No(0)
- l+a=12
t+l=4
a=t+8 or a=l+8
we can take l+a=12
l+(l+8)=12
2l=12-8=4
2l=4
so, l=2 - 10 years agoHelpfull: Yes(3) No(0)
- check by options.option a is 2,if price of lemon is 2,then it satisfies conditions of question,so price of apple is 8+2,so lemon and apple cost 12,and tomato lemon cost 4,apple is 8 more than lemon or tamato

- lem+App=12-----1
tom+lem=4-------2
app=lem+8------3
sub 3 in 1
lem+(lem+8)=12
lem=2
option a

- a)2 ans
l+a=12---- (1)
t+l=4-----(2)
a=8+l(apple is 8 more than lemon)--(3)
now (3) in (1) and solving it with (1)And (2)
we get 2t=4 => t=2
substituting t=2 in (1) we get lemon =2 - 10 years agoHelpfull: Yes(1) No(0)
- obviously ans is a.put the answers in the equation:
lemon+apple=12;
lemon+tomato=4;
only Rs.2 satisfies this two equations. - 10 years agoHelpfull: Yes(0) No(0)
- its 2 lemons/ 2 tomatos

- L+A=12
T+L=4
A=T+8=L+8
=> L+L+8=12
On solving for L
=>L=2 (ANS) - 7 years agoHelpfull: Yes(0) No(0)
- lemon + apple = 12rs
tomato + lemon = 4rs
then apple = 8+tomato or 8+lemon
by solving we get
l(8+l)= 12
2l = 4
l = 2 - 5 years agoHelpfull: Yes(0) No(0)
- Given that,
Lemon+apple=12---------1
tomato+lemon=4---------2
condition is apple=tomato+8---------3
or
apple=Lemon+8---------4
therefore,
substitute 4 in 1
lemon+lemon+8=12
2*lemon=12-8
2*lemon=4
lemon=4/2
lemon=2 - 5 years agoHelpfull: Yes(0) No(0)
