Answer:
Yusuf = 37.5
Ajay = 13.5
Step-by-step explanation:
Lets say.. Yusuf = y and ajay = a
y = 24+a (since yusuf is 24 years older than ajay)
5 years before, the sum of their ages was 41 so subtract 5 from y and a and add the two.
(y-5)+(a-5)=41
We already have defined y in terms of a (y =24+a) so we substitute that in for y.
(24+a-5)+(a-5)= 41
24-5 = 19
19+a+a-5=41
a+a = 2a
2a+19-5 = 41
19-5 = 14
2a+14 = 41
subtract 14 from both sides
2a=27
a=13.5
substitute that in y=24+a
y=24+13.5
y=37.5
lets check these answers.
(37.5-5)+(13.5-5)= 41
37.5-5 = 32.5 and 13.5-5= 8.5
32.5+8.5=41??

Let the price before increase be Rs.100
Then , as the tpercentage increase =25%
Therefore, increase in price =
100
25
×100
=Rs.25
Therefore increased price =Rs.125
Therefore the percentage by which house wife should decrease the consumption be(
