Question

At Jammu temperature was $-5^o$C on Monday and then it dropped by $2^o$C on Tuesday. What was the temperature of Jammu on Tuesday

Answer 1

Here initially temperature $t_1$ is$-5^{0}C$ (on Monday )

then on Tuesday temperature $t_1$ is dropped by $2^{0}C$ and became $t_2^{\circ }C$

so what is $t_2^{\circ }C$

here,

$t_2=(t_1-2{)}^{0}C$

$t_2=-5-2^{0}C$

$t_2=-7^{0}c$

so , on Tuesday temperature was $t_2=-7^{0}C$
