What least number must be subtracted from each of the numbers 14, 17, 34 and 42 so that the remainders are proportional ?
Let $$x$$ must be subtracted.
=> $$\frac{14-x}{17-x}=\frac{34-x}{42-x}$$
=> $$(14-x)(42-x)=(34-x)(17-x)$$
=> $$588-14x-42x+x^2=578-34x-17x+x^2$$
=> $$56x-51x=588-578$$
=> $$5x=10$$
=> $$x=2$$
