Question

if P,Q,R and S are distinct two digit number divisible by 7 then max value of (P*Q - R*S)

Answer 1

Answer:

8624

Step-by-step explanation:

For getting the maximum value of this question p x q should have the maximum value possible while r x s should have the minimum value possible. you are given that all these numbers are divisible by 7 so largest two digit numbers divisible by 7 are 91 and 98. The least 2 digit numbers divisible by 7 are 14 and 21. the four we have to do like 91 X 98 - 14 x 21 which gives the answer 8624.
