Question

What is the lenght of the truck ? Best one will get 101rs paytm from my side

Answer 1

$Observe \:the \:figure:$

$Let \: length \:of \:\the \: car = a \: m$

$Let \: length \:of \:the \:bike = b \: m$

$Let \: length \:of \: the \:Truck = c \: m$

$a + 12 = b + c \: ---(1)$

$b + 18 = c + a \: ---(2)$

/* Add Equations (1) and (2) , we get */

$\implies a + 12 + b + 18 = b + c + c + a$

$\implies 30 = b + a + 2c - a - b$

$\implies 2c = 30$

$\implies c = \frac{30}{2}$

$\implies c = 15 \: m$

Therefore.,

$\red {length \:of \: Truck } \green { = 15 \:m }$
