Answer:
Number of problems solved by Dominic is 8.
Number of pages read by Dominic is 16.
Step-by-step explanation:
Let us assume the number of problems solved by Dominic = x
So, the number of pages read by Dominic = 2 times x = 2 x
So, time taken to solve x problems = x ( Time taken to solve 1 problem)
= x ( 5 minutes) = 5x
and, time taken to read y pages = y ( Time taken to read 1 page)
= 2x ( 3 minutes ) = 6 x
So, total time taken to solve x problems and read (2x) pages = 5x + 6x
⇒ 5 x + 6 x = 88
or, 11 x = 88
⇒ x = 88/11 = 8
or , x = 8
Hence, the number of problems solved by Dominic = 8
and number of pages read by Dominic = 2(x) = 2 x 8 =16
