CROSS MULTIPLICATION METHOD WORKSHEETS

Cross multiplication method worksheet contains some practice questions. You can try each questions on your own if you find it difficult to do any problems you can just click the solution link to get clear solution with detailed explanation.

Solve the following system of equations using cross multiplication method

(i)   3 x + 4 y = 24, 20 x - 11 y = 47  Solution

(ii)  0.5 x + 0.8 y = 0.44 , 0.8 x + 0.6 y = 0.5   Solution

(iii) (3x/2) - (5y/3) = -2 , (x/3) + (y/2) = 13/6   Solution

(iv) (5/x) - (4/y) = -2 , (2/x) + (3/y) = 13   Solution

Formulate the following problems as a pair of equations,and hence find their solutions:

(i) One number is greater than thrice the other number by 2. If 4 times the smaller number exceeds the greater by 5, find the numbers. Solution

(ii) The ratio of income of two persons is 9:7 and the ratio of their expenditure is 4:3.If each of them manages to save $2000 per month, find their monthly income.  Solution

(iii) A two digit number is seven times the sum of its digits. The number formed by reversing the digits is 18 less than the given number. Find the given number.  Solution

(iv) Three chairs and two tables cost $700 and five chairs and three tables cost $1100.What is the total cost of 2 chairs and 3 tables.  Solution

(v) In a rectangle,if the length is increased and breadth is reduced each by 2 cm then the area is reduced by 28 cm ². If the length is reduced by 1 cm and the breadth is increased by 2 cm,then the area increases by 33cm². Find the area of the rectangle.   Solution

(vi) A train traveled a certain distance at a uniform speed. If the train had been 6 km/hr faster,it would have taken 4 hours less than the scheduled time. If the train were slower by 6 km/hr, then it would have taken 6 hours more than the scheduled time. Find the distance covered by the train.       Solution
