Question

pen pencil cost rupees 15 find the cost of two dozen pencil​

Answer 1

Answer:

A dozen is 12, a score 20. of course you could calculate the price of one pencil, but

I hate fractions

This is mathematics, not kindergarten arithmetic

We calculate the greatest common divisor of 12 and 20, by Euclid’s algorithm:

20≡8mod12, 12≡4mod8, 8≡0mod4

so 4 is the GCD. We find the price of 4 pencils =21/3=$7. So the price of 20 pencils is 5×$7=$35.
