1184

Explanation:

Given :

No. of parts made by machine A in 10 minutes = 7

No. of parts made by machine A in 10*6 minutes (1 hour) = 7 * 6 = 42 parts

No. of parts made by machine A in 12 hours as

required in problem = 42 * 12 = 504

No. of parts made by machine B in 15 minutes = 17

No. of parts made by machine A in 15*4 =60 minutes (1 hour) = 17 * 4= 68 parts

No. of parts made by machine B in 10 hours as

required in problem = 68 * 10 = 680
