Answer 1

Answer:

247500

Step-by-step explanation:

A speculation is a resource or thing gained determined to create pay or appreciation. Appreciation alludes to an expansion in the worth of a resource after some time. At the point when a singular buys a decent as a speculation, the purpose isn't to consume the upside yet rather to involve it in the future to make riches.

A man contributes half of the sum he has in 4% stock at 90

also, the other half in 8% stock at 110.

Assuming he had put the aggregate sum in the 8% stock at 110 he would have made 3500 more.

Allow say to add up to venture = 200

Interest in each = 100 A

4% stock at 90 = ( 100/90 ) 4A = 40A/9

8% stock at 110. = (100/110) $\times$ 8A = 80A/11

Absolute = 40A/9 + 80A/11

= ( 440A + 720A)/99

= ( 1160A)/99

aggregate sum in the 8% stock at 110 = (100/110) $\times$ 16A = 160A/11

160A/11 = ( 1160A)/99 + 3500

=> 16A/11 = ( 116A)/99 + 350

=> 144A = 116A + 350$\times$99

=> 28A = 350 $\times$ 99

=> A = 1,237.5

=> 200A = 247500

venture made = 247500
