Question

A boy bought 4 ties 6 shorts and 5 shirts for rupees 2551. One shirt and one tie cost rupees 490 while one shorthand one tie cost rupees 270. Find the cost of one tie one short and one shirt.

Answer 1

Answer:

543

Step-by-step explanation:

Let tie be = t

Let shorts be = s

Let shirts be = y

y + t = 490 ------ 1

s + t = 270 -------2

subtract equation 1 & 2.

y-s=220

⇒y=220+s

from equation 2

t= 270-s

now substitute the values of y & t in equation: 4t+6s+5y=2551

⇒4(270-s)+6s+5(220+s)=2551

⇒1080-4s+6s+1100+5s=2551

⇒2180+7s=2551

⇒s=(2551-2180)/7

⇒s=53

y=217          ---(220+s)

t=273          ---(270-s)

add s,t and y
