1). DE║AB                                              1). Given

2). ∠CDE ≅ ∠CAB                                2). Corresponding angles

                                                [Since DE║AB and AC is the transverse]

3). ∠CED ≅ ∠CBA                                3). Corresponding angles

                                                [Since DE║AB and BC is the transverse]

4). ΔABC ~ ΔDEC                                 4). By AA property of similarity    

Hence ΔABC is similar to ΔDEC.

4. Neelam's annual income is Rs. 288000. Her annual savings amount
Vikki [24]

Answer:

The ratio of her savings to expenditure <u>1 : 7</u>.

Step-by-step explanation:

Given:

Neelam's annual income is Rs. 288000.

Her annual savings amount  to Rs. 36000.

Now, to get the ratio of her savings to her expenditure:

So, we get the expenditure first:

Expenditure = Income - Savings.

Expenditure = 288000 - 36000 = Rs. 252000.

Now, <em>the ratio of savings to expenditure:</em>

\frac{Savings}{Expenditure} =\frac{36000}{252000}

\frac{Savings}{Expenditure} =\frac{1}{7}

Thus, Savings:Expenditure = 1:7.

Therefore, the ratio of her savings to expenditure 1 : 7.
