ATQ, Let us assume that Veena takes 'v' days to complete the work. One days work of Anita will be = ((100 + 1100)/100) × (1/v) = (12/v) Anita takes (v/12) days to complete the work. [1/(24 × 6)] = (1/v) v = 144 days Anita takes 12 days and veena takes 144 days to complete the work. [(120/100) × (1/12)] + [(360/100) × (1/144)] = (1/8) = Anita with 120% of her efficiency and veena with 360% of his efficiency they together can complete the work in 8 days. Hence the two blanks are 12, 8
