Three numbers A,B,Care in ratio 1:2:3. Their average is 600. If A is increased by
10% and B is increased by 20%, then to get the average increased by 5%, C will increased by:
a)90
b)100
c)150
d)180
ans
Let be A= x, B=2x, and C=3x.
(x+2x+3x)/3=600
this will be x=300
so, the numbers will be 300,600,900
new average= 105%of 600= 630
Let 110% of 300+80% of 600 + y= 630*3
solve it for y, you will get, y=1080
so, increase in C= 1080‐900 =180 ans



=========================
A and B together can complete a work in 12 days. A alone can complete it in 20 days.
If B does the work only for half a day daily, then in how many days A and B together
will complete the work?
A. 10 days B. 11 days
C. 15 days D. 20 days
ans
see ,
here given that A and B can do the work in 12 days
so A+B 1 day work = 1/12 unit.................................(1)
also given that , a alone can finish the work in 20 days
therefore
A 1 day work = 1/20 unit........................................(2)
using 1 and 2
we get,
B's 1 day work =1/12 ‐ 1/20
=1/30..............................(3)
‐‐‐> b can do the complete work in 30 days
now according to statement
if b does the work only half a day then it takes double days (i.e. 60) to complete the work
so now B 1 day work = 1/60.
also we know
A 1 day work = 1/20
now,
A+B 1 day work = 1/60 + 1/20
= 4/60
= 1/15 unit work
hence ,
A and B together will complete the work in " 15 DAYS " (answer)

ans
5 women's 1 day work=1/14
ans= 1/14 + 1/14
= 1/7 units of work
so 7 days
