Question

54 girls make 270 garlands in 1 hour how many garlands will 9 girls make in 3 hours

Answer 1

Garlands made by  54 girls in 1 hour =  270

so Garlands made by 1 girl in 1 hour = 270/54 = 5

⇒ garland made by 9 girl in 1 hour = 5 × 9 = 45

⇒ garland made by 9 girl in 3 hour = 45  ×  3 = 135

Hence 135 garlands will be made by 9 in 3 hours

Answer 2

M1= 54

W1= 270

H1= 1

M2= 9

H2= 3

W2= ?

M1*H1/W1 = M2*H2/W2

54*1/270 = 9*3/W2

1/5 = 27/W2

W2 =27 * 5

W2 = 135 Garlands
