Kanta has five dozen chocolates. She gives $\frac{1}{6}$ of these to Aruna and $\frac{1}{5}$ of the remaining chocolates to Radha. She then gives $\frac{1}{8}$ of the remaining chocolates to each of her other three friends. How many chocolates does Kanta have now?

The correct option is 25.

Let us solve this problem step-by-step to find the number of chocolates Kanta has left.

Step 1: Find the total number of chocolates Kanta starts with.
Kanta has five dozen chocolates.
Since one dozen contains 12 items:
Total chocolates = $5\times 12=60$ chocolates.

Step 2: Calculate the chocolates given to Aruna.
She gives $\frac{1}{6}$ of these chocolates to Aruna.
Chocolates given to Aruna = $\frac{1}{6}\times 60=10$ chocolates.
Remaining chocolates after Aruna = $60-10=50$ chocolates.

Step 3: Calculate the chocolates given to Radha.
She gives $\frac{1}{5}$ of the remaining chocolates to Radha.
Chocolates given to Radha = $\frac{1}{5}\times 50=10$ chocolates.
Remaining chocolates after Radha = $50-10=40$ chocolates.

Step 4: Calculate the chocolates given to her other three friends.
She gives $\frac{1}{8}$ of the remaining chocolates to each of her other three friends.
Chocolates given to each friend = $\frac{1}{8}\times 40=5$ chocolates.
Since there are 3 such friends, the total chocolates given to them = $3\times 5=15$ chocolates.

Step 5: Calculate the remaining chocolates Kanta has now.
Chocolates left with Kanta = $40-15=25$ chocolates.
