The pattern followed here is: In each row: 2nd number = (1st number + 21) , 3rd number = (2nd number - 15) In row 1, 1st number = 35, 2nd number = (35 + 21) = 56, 3rd number = (56 - 15) = 41 In row 2, 1st number = 74, 2nd number = (74 + 21) = 95, 3rd number = (95 - 15) = 80 Similarly, In row 3, 1st number = 22, 2nd number = (22 + 21) = 43, 3rd number = (43 - 15) = 28 So, ‘43’ will come in the place of question mark.
7 men and 4 boys can complete a work in 6 days. A man completes double the work than a boy. In how many days will 5 men and 4 boys complete the work?
30 men can complete a work in 12 days. After 9 days, 15 more men joined them. How many days will they now take to complete the remaining work?
If 12 men working 12 hours a day can make 12 quilts in 12 days, then in how many days 24 men working 24 hours per day will make 24 quilts?
