Question

1. The cost price of a machine is Rs. 2, 50, 000. If the rate of depreciation is 10% per year
find the depreciation in price of the machine after two years.
2. In the adjacent figure, parts shown by identical marks are congruent. State the test and
the one to one correspondence of the vertices by which triangles are congruent and​

Answer 1

$\huge \bf \red a \blue n \green s \orange w \purple e \pink r$

•Here, P = Cost price of machine = Rs 2,50,000

• R = Rate of depreciation

•per year = 10%

• N = 2 years

• A = Depreciated price of the machine after 2 years

_________________________________

----------------------------------------------------------

= 2,500 × 81 = Rs 2,02,500

Depreciation in price = Cost price (P) – Depreciated price (A) = 2,50,000 – 2,02,500

= Rs 47,500

∴ The depreciation in price of the machine after 2 years would be Rs 47,500.

2. In APRQ and ATRS,

side PR = side RT (given)

side QR = side RS (given)

ZPRQ = ZSRT (vertically opposite

angles)

:: By SAS test, APRQ = ATRS.

.. side PQ = side ST,

ZQPR = STR,

ZPQR = STAR.
