Question

If a number, $t$, is added to each of the numbers, the new sum would be $4.22$. What is the value of $t$?
$0.650.850.38+0.86$

• A. $0.24$
• B. $0.29$
• C. $0.33$
• D. $0.37$

Answer 1

The correct option is D $0.37$

If a number '$t$' is added to each of the number, then according to the question

$\Rightarrow 0.65+t+0.85+t+0.38+t+0.86+t=4.22$

$\Rightarrow 2.74+4t=4.22$

$\Rightarrow 4t=4.22-2.74$

$\Rightarrow 4t=1.48$

$\Rightarrow t=\frac{1.48}{4}$

$\Rightarrow t=0.37$
