Solution with Explanation:
Let the male students and female students be 7x and 3x respectively
7x+3x = 30000
x = 30000/10 = 3000
Therefore no. of female students = 3x = 9000
No. of female students opting for higher education = (8/100)*9000
= 8* 90 = 720
Let the money given to Hema, Rekha, Jaya and Sushma be 2x, 3x, 7x and 5x
2x+ 3x+ 7x+5x = 20000
17x = 20000
x = 20000/ 17
= Rs. 1176.4
Money to Hema = 2x = 2* 1176.4 = 2352.8 = Rs. 2353 (approx.)
Money to Sushma = 5x = 5 * 1176.4 = Rs. 5882
Equal amount to Jaya and Sushma = (2353 + 5882)/ 2 =Rs. 4117.5
Money that should be given to Hema = 4117.5 – 2353
= Rs. 1764.5
Let the water and other contents be 7x and 3x respectively
7x + 3x = 500
x = 50 ml.
Quantity of water in Sambhar = 7*50 = 350 ml.
Since the speed is constant, therefore
40:3 :: x:18
40/3 = x/18
x = (40*18)/3
= 240 kms
Let the numbers be x and 3x respectively.
3x = 2x+ 27
X = 27
Greater number = 3x = 3* 27 = 81
Let the prices of the sunglasses of Rayban and Titan Eye be 7x and 2x respectively.
7x / (2x + 1000) = 2/1
7x = 4x + 2000
x = 2000/ 3 = Rs. 666.66 = Rs.667 (approx.)
Original Price of Sunglass of titan eye= Rs. 666.66
Let the number of Rs. 2 , Rs. 5 and Rs. 10 coins be 5x, 4x and 2x respectively.
2*(5x) + 5* (4x) + 10 (2x) = 200
10x + 20x+ 20x = 200
x = 200/ 50 = 4
No. of Rs. 5 coins = 4x = 4* 4 = 16 coins
Let the pension of A, B and C be 3x, 5x and 2x.
3x + 5x+2x = 300000
10x = 300000
x = 300000/10 = Rs. 30000
Existing pension of C = 2x = Rs. 60000
Equal Pension = 300000/3 = 100000
To be added = 100000- 60000
= Rs. 40000
1 quintal = 100 kgs
Since t is in proportion
100/1000 = 86/x
1/10 = 86/x
x = Rs. 860
