41. Assuming that a man can complete the work alone in x days, his work in four days would be: a) b) X X C d) 4x x 42. If a man alone takes x days to complete the work while a boy takes y days to complete the work. The equation representing case 1 is given by: a)- + = 5 b) 6 = 4 + = у 5 + 5 d) = X 43. As per the case study, In how many days can a man alone complete the work. a) 35 days b) 70 days c) 50 days d) 100 days 44. For the equation + * = — if is taken as “a' and + is taken as 'b', the equation у
