Answer» Rs 2700 was total amount INVESTED Step-by-step explanation: Let say first sum = 4A Then Second sum = 5A ( as one fourth of 1st sum = one fiffth of second sum) Simple interest = P * R * T /100 Interest on 4A = 4A * 6 * 2 /100 = 48A/100 Interest on 5A = 5A * 7 * 2 /100 = 70A/100 Total Interest = (48A + 70A)/100 = 118A/100 118A/100 = 354 => A = 300 4A = 1200 5A = 1500 Total Sum invested = 1200 + 1500 = 2700 Rs Rs 2700 was total amount invested LEARN more: Satish invested rs. 14,000 partially in scheme A which offer 20%p.a. ... brainly.in/question/13306571 From a sum one third is invested at 3% one sixth at 6% and the rest ... brainly.in/question/4778731 Rs. 7200 was invested partly in scheme a for 6 years and partly in ... brainly.in/question/11670759

Answer»

Step-by-step explanation:

Let say first sum = 4A

Then Second sum = 5A ( as one fourth of 1st sum = one fiffth of second sum)

Simple interest = P * R * T /100

Interest on 4A = 4A * 6 * 2 /100

= 48A/100

Interest on 5A = 5A * 7 * 2 /100

= 70A/100

Total Interest = (48A + 70A)/100

= 118A/100

118A/100 = 354

=> A = 300

4A = 1200

5A = 1500

Total Sum invested = 1200 + 1500 = 2700 Rs

Rs 2700 was total amount invested
