Answer 1

Answer:

Let the sum lent =x

Rate =4%

T=8

S.I in years =

100

x×4×8

=

25

8x

ATP,

x−

25

8x

=3400

⇒25x−8x=25×3400

⇒17x=25×3400

⇒x=5000

Hence, Sum of money lent =5000.

Answer 2

Answer:

29,200 is the right answer for this.

Step-by-step explanation:

total interest= 144+208

= $352

total time = 45days + 65days

=110days

rate= 4%

P = I × 100/ R×T

= 352 × 100/ 4× 110/365days ( as the rate is per annum we need to convert days to year , hence divide by 365days)

= $29,200
