- In a total monthly income of Kiran spends 25% of his income on Rent and 20 % on travelling expenses. 40 % of the remaining income for food and while the remaining income is saved which is equal to Rs. 16500, then find his actual income?
Rs. 50000Rs. 54000Rs. 40000Rs. 30000Rs. 35000Option A

X * (25 + 20)/100 * (60/100) = 16500

X*(55/100)*(60/100) = 16500

X = 16500*(100/55)*(100/60)

X = Rs. 50000 - Sai gave 65% of the amount he had to Ria. Ria gave 2/5th of what he received from Sai to Suma. After paying Rs. 320 to the taxi driver out of the amount he gets from Ria, Suma is now left with Rs. 1500. How much amount did Sai have?
50006000700080009000Option C

Let Sai’s amount be x,

Suma now having the amount of 1500,

=>(x*(65/100)*(2/5)) – 320 = 1500

= > x*(65/100)*(2/5) = 1820

= > x= 1820*(100/65)*(5/2) = Rs. 7000

Sai initially having an amount of Rs. 7000 - In a city 62% of the population is men and remaining are women. Out of the men 74% are educated and remaining is uneducated. Out of women 65% are educate and remaining is uneducated. If total number of uneducated population is 29420, then the population of the city is?
10000020000030000040000050000Option A

(62/100) * x * (26/100) + (38/100) * x * (35/100) = 29420

=> 403x/2500 + 133x/1000 = 29420

=> 1471x/5000 = 29420

= > x = 29420*(5000/1471)

=> x = 100000 - M scored 45% marks and failed by 18 marks. N scored 54% marks and get 27 marks more than the passing marks. What is the score of P in the same examination, who secured 75 % marks?
325355375425435Option C

= > 45 % of total marks + 18 = 54 % of total marks – 27

= > 18 + 27 = (54 – 45) % of total marks

= > 45 = 9 % of total marks

= > Total marks = 45*(100/9) = 500

P’s mark = (75/100)*500 = 375 - Find the total number of votes cast in the election if one who got 40 % votes lost by 400 votes.
10002000300040005000Option B

One person got 40 % and another person got 60 %

According to the question,

(60 – 40) % of the votes = 400

20 % of the votes = 400

Total votes = 400*(100/20) = 2000 - A motorist bought two bikes Rs.2400 each. He sell one at 10% profit and another at x% loss in the whole transaction there is no profit or loss, and then find the value of ‘x’
1015202530Option A

2400*110/100+2400*(100-x)/100=4800

=>2400*(100-x)/100=4800-2640

Simplify the above equation, we get x=10% - A vendor marks 50% above the CP and sell at 20% discount. If the profit is double the discount and the discount rate is same, then vendor marks what % more than the CP?
406080100120Option D

Let us take CP Rs.100

MP = 150

SP= 150*80/100=120

Profit = 120-100=20

Incase profit = 60

SP= 160

MP=160/80*100=200

Required percentage = 100/100*100=100% - Priti sell an Box at 10% profit. If she bought it 20% less and sell Rs.50 more she gains 100% profit, and then find the cost price of a box.
100150200250300Option A

Let us take CP of a box be x

SP = 110/100 *x

CP= 80/100*x

SP=110/100 *x+50=200/100*80/100*x

5/10*x=50=>x=100 - A shopkeeper got a cooker for Rs. 8100. He allows a discount of 10% on its marked price and still gains 15%. Find the marked price of the cooker?
Rs. 10350Rs. 10500Rs. 11290Rs. 10320Rs. 12450Option A

Selling price = 8100*(115/100) = Rs. 9315

Marked price*(90/100) = 9315

Marked price = 9315*(100/90) = Rs. 10350 - The profit earned by selling a Wooden cot for Rs. 2540 is the same as the loss incurred by selling the Wooden cot for Rs.1640. At what price should it be sold to make a 30% profit?
Rs.1317Rs.3717Rs.2717Rs.2007Rs.1117Option C

CP = (1640+2540)/2 = 4180/2

= Rs. 2090

SP = 2090 * 130/100 = Rs.2717
