pie chart quiz 1

The required ration = (16 + 21)% (9000) : 8% (45000)
⇒
⇒ 37 : 8 x 5
⇒
⇒ 37 : 40

Qualified candidates from B and C = (16 + 7)% = 23% (9000)
Appeared candidates from B and C = (11 + 8)% = 19% (45000)
So required percentage =
(23%(9000)/19%(45000))×100
=
(23/19×5)×100
= 24.21
23%(9000)19%(45000)×100=2319×5×100=24.21

Instead of calculating qualified candidates for D and G
separately, we take the difference in their percentages.
i.e., 8% (9000) = 720.

This is a lengthy question. But we will use simple technique
to solve this question.
We have to calculate the ratio of Qualified to appeared
for each state. So
Qualified candidates from A
Selected candidates from A
×
100
=
18
%
×
9000
15
%
×
45000
×
100
Qualified candidates from ASelected candidates from
A×100=18%×900015%×45000×100

But If you observe in the above equation, only 18% / 15%
changes for each state. Remaining values are constant.
Minimum percentage we get if numerator is small and
denominator is big.
For C it is 7/8 = 1/1.14 and for E it is 9/14 = 1/1.5
So for E denominator is big. So it has the ratio Minimum.
So Option D is correct.

There is not need to calculate values. This is simply a ratio.
So we can compare the ratio of their percentages.
C + E = 8 + 9 = 17; A + F = 15 + 18 = 33.

So ratio = 17 : 33

Required ratio = 4910 / 29952
=1 / 6.1 or 1:6 app

Central angle corresponding to Market Borrowing

= (29952 + 11486 + 5252 + 4910 + 6000) = 57600

= ( 29952/57600 x 360°) = 187.2º

Amount permitted =
(Funds required from Toll for projects of Phase II) + (10% of these funds)
= Rs. 4910 crores + Rs. (10% of 4910) crores

= Rs. (4910 + 491) crores

= Rs. 5401 crores.

Shortage of funds arranged through External Assistance
= Rs. (11486 - 9695) crores = Rs. 1791 crores.
Increase required in Market Borrowing = Rs. 1791 crores.
Percentage increase required = ( 1791 / 29952 x 100) %
= 5.98% or 6%. App.

20% of the total funds to be arranged = Rs. (20% of 57600) crores
= Rs. 11520 crores is near about Rs. 11486 crores.
Rs. 11486 crores is the amount of funds to be arranged
through External Assistance.
