Re: Rangpur Secondary 2011/6

no..actually it is if $N=15x$ [$x=1,2] and divisible by 7 then quotient is twice the remainder.

Re: Rangpur Higher Secondary 2011/3

$-3<f<1$ and $-2<g<4$
if $f=-2.90$ and $g=-1.90$ their multiple $fg$ will give a positive answer!!!
thats why $6<fg<4$

Re: Rangpur Higher Secondary 2011/7

the Left side of Equation is $A-z$ ok? So the right side is $1-2-3-4. . . . . . .-25-26$ =$1-(2+3+4+5. . . .+25+26)$ =$1-(1+2+3+4. . . .+25+26)+1$ =$2-(27*13)$ =$2-351$ =$-349$ ... There are 26 equations. When we substract 26 equation at a time the first and last variables will left on the left side...
