Question

if the ratio of the husband and wife age is 3 raise to 2 if the sum of the aged 60 years what will be the age of wife after 3 years

Answer 1

let the age of husband be x and that of wife be y
given ratio3:2
therefore 3/2=x/y
y=2x/3
given:x+y=60
x+2x/3=60
5x/3=60
x=36
y=24
after 3 years the age of wife will be 27 years

Answer 2

Answer:

Step-by-stepGiven: SP║RQ, ∠R = 90° and ∠Q = 130°.

To find: The measure of ∠P.

Answer:

It is given that SP║RQ. So let us assume that PQ is the transversal.

Therefore, ∠P + ∠Q = 180° (Co - interior Angles are Supplementary)

∠P + 130° = 180°

∠P = 180° - 130°

∠P = 50°

Now let us assume that SR is the transversal.

Therefore, ∠S + ∠R = 180° (Co - interior Angles are Supplementary)

∠S + 90° = 180°

∠S = 180° - 90°

∠S = 90° explanation:
