Question

Three kites - red, blue and yellow can go highup in the air. The combined height of red andblue kites is 160 metres, blue and yellow is140 metres, and red and yellow is 180 metresFind the height of each of the kitos​

Answer 1

Answer :

• Let the heights of red, blue and yellow kite be r, b and y respectively.

• Given that : r + b = 160, b + y = 140 and r + y =180

• Eiminate b from above first two equations by adding them.

• Now, we have r - y = 20 and r + y = 180

• Solving these, we will get r =100m

• By substituting r in the initial equations, we will get

b = 60m and y = 80m

• Hence, the heights of red, blue and yellow kite is 100m, 60m and 80m respectively.
