If the savings of A are 20% more than that of B then,
Saving of A = \(0.25Y \times \frac{120}{100} = 3Y/10\); ⇒ 0.4X = 3Y/10; ⇒ 4X = 3Y;

Let B be 100, then A will be 125 ;
Now; \( {60 \over 100}C = 100 \) then; \(C = {500\over 3}\) ;
Also, \({130\over 100}D = C = {500\over 3}\) ; then \(D= {5000 \over 3 \times 13}\) ;
\({A \over D } \times 100 = {125 \times 3 \times 13\over 5000}\times 100= {195\over 2}\)%
Since we have to calculate less than percentage it will be \(100-{195\over 2} = 2.5\) %

, 33%✓ SSC CGL 2019179)When the price of an item was reduced by 25%, then its sale was increased by x% . If there is an increase of 20% in the receipt of the revenue, then the value of x will be:
60
Revenue =\( price \times sale;\)
Let the price and sale be Rs.100 and 100 units.
Revenue = \(100 \times 100\) = Rs.10000;
ATQ,
1.2Revenue = \(100 \times \frac{75}{100} \times (100 + x)\);
\(1.2 \times 10000 = 75 \times (100 + x);

x = 160 - 100 = 60
, Avg: 02:15 , 83%✓ SSC CGL 2019180)Radha marks her goods 25% above the cost price. She sells 35% of goods at the marked price, 40% at 15% discount and the remaining at 20% discount. What is her overall percentage gain?
11.25
Let the cost price be Rs.100 and total goods be 100.
cost price of 100 goods = 10000;
Radha marks her goods 25% above the cost price.
So, marked price = Rs.125;
ATQ,
\({{125 \times 35 }\over100}+ 125 \times {85\over100} \times 40 + 125 \times {80\over100} \times 25\) =
4375 + 4250 + 2500 = 11125;
Gain = 11125 - 10000 = 1125;
Percentage gain = \(\frac{1125}{10000} \times 100\) = 11.25%
, Avg: 02:17 , 75%✓ SSC CGL 2019181)A number is first increased by 16% and then increased by 14%. The number, so obtained, is now decreased by 30%. What is the net increase or decrease percent in the original number(nearest to an integer)?
7% decrease
Let the number be x;
ATQ,
Number is first increased by 16%,
So,
Obtained number = 1.16x;
Obtained number is increase by 14%;
So, obtained number = \(1.16x \times \frac{114}{100}\) = 1.3224x;
NUmber is decreased by 30%;
So, obtained number = \(1.3224x \times \frac{70}{100}\) = 0.9256;
Net decrement = x - 0.9256x = 0.0744;
Percentage decrement = \(\frac{0.074x}{x} \times 100\) = 7.4% = 7

17.5
Let the income of Raghav be Rs.100.; Expenditure = 80; Saving = Rs.20; Income increases by 12% and the savings decrease by 10%, So, income = 112, Saving =\( 20 \times \frac{90}{100}\) = 18 ; Expenditure = 112 - 18 = 94 ;Increment in his expenditure = 94 - 80 = 14 ; Percentage increment in expenditure =\( \frac{14}{80} \times 100\) = 17.5%
, Avg: 01:41 , 80%✓ SSC CGL 2019183)A shopkeeper bought 120 quintals of wheat, 20% of it was sold at 25% loss. At what percent gain should he sell the rest to gain 25% on the whole transaction?
37\({1 \over 2}\)
Let the rate of 120 quintals be Rs.120.
For 25% gain = \(120 \times \frac{125}{100}\) = Rs.150;
20% of the 120 quintals = \(20 \times \frac{120}{100} \)= 24 quintals;
remaining wheat = 120 - 24 = 96 quintals;
20% of it was sold at 25% less;
So, selling price of 20% wheat =\( 24 \times \frac{75}{100}\) = Rs.18;
Cost price for 96 quintals wheat = Rs.96;
Selling price = 150 - 18 = 132;
Gain = 132 - 96 = 36;
Gain% = \(\frac{36}{96} \times 100 = 37\frac{1}{2}\)
, Avg: 01:05 , 60%✓ SSC CGL 2019184)If A is 28% more than B and C is 25% less than the sum of A and B, then by what percent will C be more than A (correct to one decimal place)?
33.6%
Let the B = 100;
A = 128;
C = 25% less than the sum of A and B;
C =\( (100 + 128) \times \frac{75}{100}\) = 171;
Required percentage =\( \frac{171 - 128}{128} \times 100 = \frac{43}{128} \times 100\) = 33.6%

23.1%
Let the cost price of article be Rs. 100.
Selling price of article = 100+ 30 = Rs. 130
Profit = Rs. 30
Profit percent at the selling price = \({30 \times 100 \over 130}\)
= 23.1%
