Answer:
Given that the difference between CI and SI = 768. x = 120000. therefore the sum is 120000.
Step-by-step explanation:
Answer
Let the sum be Rs. 100.
Then S.I. = Rs 100100×2×8 = Rs. 16C.I. = Rs. 100[(1+
1008 ) 2 −1]= Rs. 100[( 25÷27 ) 2 −1] = Rs100×[ 625÷729−625]= Rs. ( 625÷100×104 )= Rs. 16.64
∴ Difference = Rs. 0.64, If the difference between C.I. and S.I. is Rs. 0.64, Sum = Rs. 100
If the difference is Rs. 768 sum = Rs. Rs. ( 0.64100 ×768)= Rs. 120000
