TCS Digital Pie Chart Quiz – 1

The required ration = (16 + 21)% (9000) : 8% (45000)
⇒3330: 3600
⇒ 37 : 40

Solution:

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

Solution:

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.

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

Solution:

58% (Samsung 23% + Apple 20% + Xiaomi 15%)

Solution:

28.8° (8% of 360° = 0.08 × 360° = 28.8°)

Solution:

6 percentage points (Others 24% - (Oppo 10% + Vivo 8%) = 24% - 18% = 6%)

Solution:

Market Borrowing reduction: 15% of 32,589 = 4,888.35 crores

External Assistance's share of non-Market Borrowing funds:

Total of other sources = 13,565 + 6,750 + 5,210 + 8,500 = 34,025 crores
External Assistance proportion = 13,565 ÷ 34,025 = 0.3986 (39.86%)
Extra amount allocated to External Assistance:

39.86% of 4,888.35 = 1,948.68 crores
New External Assistance amount:

13,565 + 1,948.68 = 15,513.68 crores
Percentage increase:

1,948.68 ÷ 13,565 × 100 = 14.37%
The closest answer is 15,623 crores; 15.17% increase

Solution:

To find the percentage of Market Borrowing:

Calculate the total funding = 32,589 + 13,565 + 6,750 + 5,210 + 8,500 = 66,614 crores
Calculate the percentage: (32,589 ÷ 66,614) × 100 = 48.92%
Round to 49%
