Given:
Total sum paid = Rs. 6240
Number of instalments = 30
Increase in each instalment = Rs. 10
To find:
Value of the 1st instalment
Solution:
Let the value of the first instalment be x.
Then, the value of the second instalment will be x + 10.
Similarly, the value of the third instalment will be x + 20 and so on.
Since there are 30 instalments, the value of the last instalment will be x + (30-1) * 10 = x + 290.
The total sum paid off in 30 instalments is given to be Rs. 6240.
So, we can write the equation:
x + (x+10) + (x+20) + ... + (x+290) = 6240
Simplifying the equation, we get:
30x + 4350 = 6240
30x = 1890
x = 63
Therefore, the value of the first instalment (x) is Rs. 63.
Hence, the correct option is (D) none of these.
