Triplicate Ratio

Find the : (i) duplicate ratio of 2sqrt(2) : 3sqrt(5) (ii) triplicate ratio of 2a : 3b , (iii) sub-duplicate ratio of 9x^(2)a^(4) : 25y^(6)b^(2) (iv) sub-triplicate ratio of 216 : 343 (v) reciprocal ratio of 3: 5 (vi) ratio compounded of the duplicate ratio of 5 : 6 , the reciprocal ratio of 25 : 42 and the sub-duplicate ratio of 36 : 49 .

Mr. Mehta and Mr. Yadav are neighbours in the ‘Populated Colony’. The ratio of the number of sons and daughters Mr. Yadav has is equal to the duplicate of the sub triplicate ratio of the number of sons and daughters Mr. Mehta has. The daughters in any of the houses are more in number than the sons. If both the neighbours have an equal num- ber of daughters, what is the minimum strength of the total children in both the houses?

Find the ratio compounded of the reciprocal ratio of 15 : 28 , the sub-duplicate ratio of 36 : 49 and the trilicate ratio of 5 : 4 .

If the triplicate of the ratio (x+a) : (x + b) " is " a : b , then prove that x^(3) - 3abx - ab(a +b) = 0 .

If the triplicate of (x+a)/(x+b) " is " a/b , that show that x^(3) - 3 abx - ab (a +b) = 0 .
