Question

Please answer this.This is going to be in my test.

In the equation p×q=r; if p is increased by13 and q remains unchanged; there r is increased by 65. If q is increased by 13 and p remainds unchanged; then find r is increased by 104. Find the value of r.

Answer 1

Answer:

Step-by-step explanation:

(P+13)*Q= (R+65) -equation 1

P*(Q+65)= (R+104) -equation 2

P*Q=R. - equation 3

PQ+13Q=R+65------1

PQ+65P=R+104------2

#From 1 and 3#

R+13Q= R+65

13Q =65

HENCE Q = 5

# From 2 and 3

R+13P= R+ 104

13P=104

HENCE P=8

# FROM RESULTS WE FOUND#

R= P * Q

= 8*5

= 40

R= 40
