Question

If 2.516 can be written as 2+5×0.1+y×0.0001+x0.01 then value of x+y is ??​

Answer 1

Answer:

here is ur answer

given expression is=

2+5×0.1+y×0.0001+0.01x this is equal to 2.516

we can simplify it

2+0.5+0.0001y+0.01x=2.516

2.5+0.0001y+0.01x=2.516

0.0001y+0.01x=0.016

multiplying by 1000

0.1y+10x=16

multiplying by 10

y+100x=160

now we require x+y

we can assume x=1 and y=60 or any other value as it is a linear equation

x+y=61 or it varies as per selection of x and y .. kindly tell me the answer given in the book of this question
