Question

if 5/2 of 2/5 of 20% of a number is 252 then find the number​

Answer 1

Solution:

$\frac{5}{2} \times \frac{2}{5} \times \frac{20}{100} \times x = 252 \\ x = \frac{252 \times 10}{2} \\ x = \frac{2520}{2} \\ x = 1260$

1260 is the number

Answer 2

Answer:

Missing number is $1260$ .

Step-by-step explanation:

To find : missing number .

Given : $\frac{5}{2}$ of $\frac{2}{5}$ of $20\ \%$ of a number is $252$ .

Solution :

• Let  missing number be $x$ .
• According to given condition we write as , $\frac{5}{2}\times\frac{2}{5} \times\frac{20}{100} \times x = 252$ .
• Using transposition method , we find the value of $x$ , by transposing constants at RHS and leaving variables at LHS .

         $\frac{5}{2}\times\frac{2}{5} \times\frac{20}{100} \times x = 252\\\\\frac{20}{100} \times x = 252 \\\\x = 252\times \frac{100}{20} \\\\x = 252 \times 5\\\\x = 1260$
