A playgroup has a number of tricycles and bicycles. Tha sum of the wheels is 60 and the sum of the saddles is 24. How many tricycles does the playgroup own

Question

Step by step answer

Answer 1

If T=number of 3-wheeled and one-saddled tricycles and B=the number of 2-wheeled and one-saddled bicycles,  we have:

3T+2B=60 and T+B=24, so B=24-T. Substitute for B in the other equation:

3T+2(24-T)=60, 3T+48-2T=60, T+48=60, T=12 so B=12.

The number of tricycles is 12.
