Answer 1

54 answer is in words / minute

Answer 2

Method -

Work 1 = 1 ( No. of assignments)

Work 2 = 1 ( No. of assignments)

Efficiency 1 = 50 Words ( No. of words asha can type)

Effeciency 2 = x (No. of words shneha types)

Time 1 = 45 Minutes

Time 2 = 30 Minutes

W1/W2 = M1*T1 / M2*T2

1/1 = 50*45/30*x (Linear equation)

x = 50*45/30

x = 2250/30

x = 225/3

x = 75
