Question

In Shimla, on Tuesday the temperature was $-8^0$C. It then dropped by $4^0$C on Wednesday. On Thursday, it raised by $x$. If the temperature on Thursday is $-7^0$C, then find the value of $x$.

• A. $4^0$C
• B. $5^0$C
• C. $7^0$C
• D. $2^0$C

Answer 1

The correct option is B $5^0$C

Tuesday temperature at Shimla $=-8^{o}C$

Wednesday temperature at shimla $=-8^{o}C-4^{o}C=-{12}^{o}C$

On Thursday temperature raised by $x$.

Thursday temperature is $-7^{o}C$.

$\therefore$ $-{12}^{o}C+x=-7^{o}C$

$\therefore$ $x=5^{o}C$
