4. Ramesh has enough money for 6 weeks if he spends Rs 1400 per week during summer vacation. How long will the money last if he spends Rs 1050 per week? Solution( By Unitary Method) : Here we have to find out nos. of weeks.

Therefore multiplication has been done. ∴ By spending Re 1050 per week the money will last for (6x1400)/1050 weeks. (30x8)/20 people. Explanation:For Rs 1050 per week spending, the money will lasts for less numbers of weeks in comparison to previous spending of Re 1 per week.

3. Eight people eat a stock of food in 30 days. How many people will consume the stock of food in 20 days? Solution( By Unitary Method) : Here we have to find out nos. of people. Therefore we will keep the people at right side in the statement. &#x2235 In 30 days a stock of food is eaten by 8 people. ∴ In 1 day same stock of food will be eaten by 30x8 people. Explanation: For 1 day more nos. of people will be needed to eat the same stock of food. Therefore multiplication has been done. ∴ In 20 days same stock of food will be eaten by (30x8)/20 people. Explanation: For 20 days lesser nos. of people will be needed to eat the same stock of food. Therefore division has been done.,/p>= 240/20 = 12 people Ans.

( explanation: in 1 day more men will be needed to complete the same job, therefore for more men multiplication has been done.)∴ To complete the job in 40 days the required men are (20x4)/40 . explanation:lesser number of men will be needed to complete the job in 40 days in comparison to one day. Therefore division has been by 40= 80/40 = 2 men Ans.

1.Three men do a job in 8 days. How long will 4 men take to finish the job? Solution( By Unitary Method) : Here we have to find out days. Therefore we will keep the days at right side in the statement. &#x2235 3 men complete the job in 8 days∴ 1 men complete the job in 3x8 days. ( explanation: one man will take longer to complete the same job, therefore for more days multiplication has been done.)∴ 4 men complete the job in (3x8)/4 explanation: 4 men will take lesser time to complete the same job in comparison to 1 man, therefore for less days division by 4 has been done.= 24/4 , = 6 days Ans.
