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...
