If he had worked the full time he would have earned an extra Rs 270 in 3 more weeks. He is therefore earning Rs 90 per week.
In four weeks he would earn 4 x 90 = Rs 360.
For that he received a holiday and Rs 30 so the holiday must be worth Rs 330.

For 7 weeks of work the man would get Rs 300 plus the holiday (call it H). This means that
each week the man earns one-seventh of Rs 300 + one-seventh of H. In equation form this is:
.

.
But the man only worked 4 weeks and he got Rs 30 + H. That means that each week he earned
one-fourth of what he got ... for each week of work he got:
.

.
Assuming that the weekly rates remained the same in both cases, you can set them equal and
the equation is:
.

.
Let's get rid of the denominators by multiplying both sides of this equation by a common
denominator of 28 (that is multiply all terms by 7 times 4) and the equation becomes:
.

.
Next cancel the terms in the denominators with the same terms in the numerators to reduce
the equation:.
.

.
and the equation becomes:
.

.
Multiply out the two "number" terms:
.

.
Next, collect the terms containing H on one side of the equation and the numbers for Rs on the
other side. Begin by subtracting 4H from both sides of the equation:
.

.
After the subtraction the equation is:
.

.
Next subtract Rs 210 from both sides of the equation:
.

.
After the subtraction the equation is reduced to:
.

.
Finally, solve for H (the value of the holiday) by dividing both sides of the equation
by 3 and you find that:
.

.
So the answer to the problem is that the Holiday, H, is worth Rs 330.
.
You can check this by calculating that in 4 weeks the man earned Rs 30 + H or Rs 30 + Rs 330
for a total of Rs 360. If you multiply this amount by the ratio you find that
in 7 weeks he should earn:
.

.
Then you can compare this Rs 630 with the problem statement that says in 7 weeks he earns
Rs 300 + the holiday ... which is Rs 300 + Rs 330 ... a total of Rs 630. This is the same
answer we got by multiplying what he earned in 4 weeks by the ratio of so the
answer of H = Rs 330 looks good.
.
Hope this helps you to understand the problem.
