उत्तर
Let ‘x’ be the total no. of flowers Radha at first.
No. of flowers remained with her after visit to the first temple = `x/2`
No. of flowers remained with her after visit to the second first temple = `x/4`
No. of flowers remained with her after visit to the third first temple = `x/8`
Flowers remaining at last = 3
According to the question,
`x - (x/2 + x/4 + x/8) = 3`
8x – 7x = 24
x = 24
So, total number of flowers at the beginning = 24
