Question
The average height of three boys is 170 cm. If their
heights are in the ratio 6:4:7, what is the height of the tallest boy?Solution
Sum of height of boys = 3 × 170 = 510 cm
Let the height of three boys be ‘6x’ cm, ‘4x’ cm and ‘7x’ cm.
So, 6x + 4x + 7x = 510
So, x = 30
Height of tallest boy = 7x = 7 × 30 = 210 cm.
