Question

If a and b vary inversely to each other, then find the value of P, Q, R and S?
a 6 8 Q 25 S
b 18 P 39 R 3

Answer 1

Answer:

If a and b vary inversely, this means that the product of a and b is constant. Therefore, if a and b are given, we can calculate the constant by multiplying a and b together.

Given values:

a = 6, 8, Q, 25, S

b = 18, P, 39, R, 3

Here the product of a and b is constant and the formula is a*b = k(constant)

So,

618=8P=Q39=25R=S*3=k

From the above equation, we can find the values of P, Q, R, and S by solving for them using the given values of a and b.

For example:

P = 6 * 18 / 8 = 27

Q = 6 * 18 / 39 = 4.5

R = 6 * 18 / 25 = 7.2

S = 6 * 18 / 3 = 36

So, the value of P, Q, R and S are 27, 4.5, 7.2, 36 respectively.
