Liquidity ratios demonstrate a company's ability to pay its debts and other liabilities. In this type, you will find that a particular quantity (e.g .,Amount in rupees, Mixture in litres) is to be shared among individuals based on ratios. Solution: To solve this type of problems, you have to remember a simple formula shown below: Amount received by a person = (Ratio value of that person / Sum of the ratio values) x Total amount, Based on the above formula, you can easily derive the below 3 formulas: Amount received by Ram = (Ram’s ratio value / Sum of the ratio values) x Total amount Amount received by Gita = (Gita’s ratio value / Sum of the ratio values) x Total amount Amount received by Anu = (Anu’s ratio value / Sum of the ratio values) x Total amount, You know that Ram’s ratio value = 2 , Gita’s value = 3 and Anu’s value = 4 Sum of the ratio values = 2+3+4 = 9 And total amount = 5400, Therefore, you can find individual amounts as shown below Ram’s amount = 2/9 x 5400 = 1200 Gita’s amount = 3/9 x 5400 = 1800 Anu’s amount = 4/9 x 5400 = 2400. The mathematical symbol of ratio is ‘:‘ It is written as say, 1:4 and read as 1 “is to” 4. (ii) Duplicate ratio of 4 : 5 is 64 : 125, The sub–duplicate ratio of a : b is âˆša : âˆšb, (i)  Sub-duplicate ratio of 4 : 9 is âˆš4 : âˆš9  =  2  :  3, (ii)  Sub-duplicate ratio of 16 : 25 is âˆš16 : âˆš25  =  4  :  5. Now, you have to find the LCM of 8 and 6, which is 24. Therefore, a:b = 5×3:8×3 = 15:24, Consider second ratio b:c You know that b:c = 6:7 To transform b from 6 to 24, you have to multiply both the terms by 4. We can multiply all values by the same amount and still have the same ratio. If Rs 1050 is divided into three parts, proportional to (1 / 3) : (3 / 4) : ( 4 / 6), then what is the first part? Because 17 > 9, A ratio a : b is said to be of lesser inequality if a < b, 9 : 17 is a ratio of lesser inequality. Each type is explained with example. Higher the net profit ratio, the higher the net worth, and stronger the balance sheet. But a ratio can also show a part compared to the whole lot. Similarly, the triplicate ratio of a : b is a³ : b³. Example Question 4: A 15 litres of mixture contains water and milk in the ratio 2 : 4. Thus a : b is the inverse of b : a and vice–, A ratio a : b is said to be of equality if a =, A ratio a : b is said to be of inequality if a, 5 : 7 is a ratio of inequality. Thus a : b is the inverse of b : a and vice–versa.
