Question
According to a plan, a team of farmers decided to
harvest 208 cubic meters of rice in several days. In the first four days, the team fulfilled the daily assignment, and then it harvested 7 cubic meters of rice over and above the plan every day. Therefore, a day before the planned date, they had already harvested 203 cubic meters of rice. How many cubic metres of rice a day did the team have to cut according to the plan?Solution
Let the team dig x m3 per day. Then, total number of days required = (208/x) days According to questions, 4x + [(208/x) -5] (x + 7) = 203 4x +208 -5x +(1456/x) - 35 = 203 173 - x +(1456/x ) = 203
1456/x - x = 203 - 173 = 30
So either by solving this equations or putiing the value from evry option, x = 26.

What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
[192 ÷ 6 × 5] ÷ (? + 3) = 20
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 175
55% of ? = 45 + 20 × 6
