-10,-20,-30,-40,-50

? = 263 - When 50% of first number is added to the second number then second number increases by 25% . Find the ratio of first number to the second number.
3:55:71:22:51:4Option C

Let the first number be x and second number be y resp.

50% of x + y = 1.25y

=>x : y = 1:2 - A mixture of contains 360 litres of milk and water in the ratio of 5:4 resp. x litres of mixture is taken out and replaced with same quality of water such that of milk and water becomes 1:1 resp.Find the value of x.
3044362839Option C

Quantity of milk = 5/9*360 = 200 L

Quantity of water = 4/9*360 = 160 L

200 â€“ (5x/9) = 160 â€“ (4x/9)+ x

=> x = 36 L - A,B and C started a business together with a total investment of Rs.3600. After a year , A and B received a profit of Rs.1500 and Rs.2000 out of the total profit of Rs.6000. Find the inital investment of C (in Rs.)
10001500140013001200Option B

Ratio of investment of A:B:C = 1500:2000:(6000-1500-2000)

= 3:4:5

Initial investment of C = 5/(3+4+5)*3600 = Rs.1500 - The ratio of the units digit to the tens digit of two digit number is 4:1 and the sum of digits is 10. Find the product of digits of number.
1014161913Option C

Unitâ€™s digit be 4x and tenâ€™s digit be x resp.

4x+x = 10

x = 2

Required number = 28

Product of digits = 2*8 = 16 - A bag contains (x+2) red balls, (x+3) green balls and (x+4) yellow balls. If the probability of drawing a red ball from the bag is 3/10. Find the number of green balls in the bag.
1318101214Option C

Total number of balls in the bag = 3x+9

Probability of drawing a re ball = 3/10

(x+2)/(3x+9) = 3/10

=>x = 7

Total number of green balls = 7+3 = 10

Thanks for every other informative site. Where else may I am getting that kind of information written in such a perfect method? I have a venture that I am just now operating on, and I’ve been at the look out for such info.
