Question

A zoo keeper weighed some animals at zoo .He found that lion weighs 90 kg more than leapord and tiger weighs 50kg less than lion.Altogether three animals weigh 310 kg.What is the weight of lion
A.180 B.150 C.140 D.130 E.100

Answer 1

let the weight of leopard be x
and lion = x+90
and tiger = x+90-50=x+40

According to the question
(x+90)+(x+50)+x=310
x+90+x+40+x=310
3x+130=310
3x=310-130
3x=180
x=180/3
x=60

so weight of the leopard (x)= 60
then weight of lion(x+90)=60+90
=150

Answer 2

Answer:

The weight of lion is $150kg$.

Step-by-step explanation:

It is given that zoo keeper weighed some animals at zoo .

The lion weighs $90 kg$ more than leapord.

Tiger weighs $50kg$ less than lion.

Total weight $=310kg$

Assuming the weight of leapord be $x$

Weight of lion $=x+90$

Weight of tiger $=x+90-50=x+40$

As per the question

$(x+90)+(x+50)+x=310$

Solving

$x+90+x+40+x=310$

$3x+130=310$

$3x=310-130$

$3x=180$

$x=180/3$

$x=60$

The weight of lion is $x+90=60+90=150kg$
