Solution:-
Step 1:
Given 25 % of the total salary is deducted for House rent, Now left with is 75%
only
Out of this 75 % 20 % is deducted
for Education
Out of what is left over 40 % deducted for Food
Now left is Rs. 9000
Step 2: To find what is the full salary
Step 2: To find what is the full salary
Step 3:
working:
Say Rs. 100 is the total salay. Out of this 25% goes for Rent Now left is 75 Rs.
Say Rs. 100 is the total salay. Out of this 25% goes for Rent Now left is 75 Rs.
Out of
75, 20 % goes for education 20/ 100 x 75 = 1/ 5 x 75 = 15 rs.
Now
left is 75-15 – 60 rs.
Out of
this 60 40% goes for foo
ie 40/ 100 x 60 = 2/ 5 x 60 = 2 x 12 = 24Rs.
ie 40/ 100 x 60 = 2/ 5 x 60 = 2 x 12 = 24Rs.
Now
left is 25 +24+15 = 64 spent – 36 left
If 36
Rs. Left full salary is 100
If 9000
left full salary is 9000 x 100 /
36 =
1000 x100 / 4 = 25 x 10000 = Rs. 25000 Answer
Q.2.
Pass mark is 40 % marks obtained is 210, failed by 40.
Total
mark is ?
210 +
40 = 250 is the pass mark
Is 40 %
is 250
Hence
100 % = 250 + 250 + 125 = 625 marks Answer
Q.3. .The
total population of a country is 294000, out of which 150000 are males. Out of
every 100 males, 98 can read and write, but only 53% of the total population
can do so
294000-
150000 = 144000 females.
98%
males can read ie. 98/ 100 * 150000
= 147000 can read left is3000 who
cannot read
53 % of total can read is 53/ 100 x 294000 =
155820 – 147000 = 8820
Total po- male- 294000-150000=144000
147000
8820---------------144000
X----------------------100
6.125%
Ram get Rs. 100, Ramesh get 125
100/125 * 100 = 80 is 20 % less than Ramesh is the salary of Ram
