SOLUTION

GIVEN

7p24 - 594q = 1977

TO DETERMINE

The value of p + q

EVALUATION

Here it is given that 7p24 - 594q = 1977

Unit digit of 7p24 = 4

Unit digit of 594q = q

Unit digit of 1977 = 7

So the value of q must be 7

Thus 594q becomes 5947

Thus we get

7p24 - 594q = 1977

⇒ 7p24 - 5947 = 1977

⇒ 7p24 = 5947 + 1977

⇒ 7p24 = 7924

Comparing both sides we get p = 9

Hence we get

p + q

= 9 + 7

= 16

FINAL ANSWER

The value of p + q = 16
