Answer» Solution:- ━━━━━━━━━━━━━━━━━━━━━━━━━━ ❍ Here, the question has given us the S.I, PRINCIPAL and TIME that are ₹600, ₹10,000 and 3 years respectively. Now, the question has asked us to find out the rate of interest. So, we will apply the formula of Simple Interest to FUND the rate of interest. ANSWER:- The rate of interest is 2%. GIVEN:- » Simple Interest = ₹600 » Principal = ₹10,000 » Time = 3 years TO FIND:- ✰ Rate of interest = ? FORMULA:- ➛ Simple Interest = P×R×T/100 Where, S.I = Simple Interest P = Principal R = Rate T = Time SOLVING BY APPLYING THE FORMULA:- ❖ Let the rate be R ↣ 600 = 10,000 × R × 3 / 100 ↣ Cancelling the zeros. ↣ 600 = 100 × R × 3 / 1 ↣ 600 = 300 × R / 1 ↣ 600 × 1 = 300 × R ↣ 600 = 300 × R ↣ 600 / 300 = R ➛ 2 = R Hence, we GOT the answer. The rate of interest is 2%. TO CHECK:- P = ₹10,000 R = 2% T = 3 years ⇨ Simple Interest = P × R × T / 100 ⇨ S.I = 10,000 × 2 × 3 / 100 ⇨ S.I = 10,000 × 6 / 100 ⇨ Cancelling the zeros ⇨ S.I = 100 × 6 / 1 ⇨ S.I = 100 × 6 ⇨ S.I = 600 Hence, checked.

What rate gives ₹600 as interest on the sum of ₹10000 in 3 years?

Answer»

Solution:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

❍ Here, the question has given us the S.I, PRINCIPAL and TIME that are ₹600, ₹10,000 and 3 years respectively. Now, the question has asked us to find out the rate of interest. So, we will apply the formula of Simple Interest to FUND the rate of interest.

ANSWER:-

The rate of interest is 2%.

GIVEN:-

» Simple Interest = ₹600

» Principal = ₹10,000

» Time = 3 years

TO FIND:-

✰ Rate of interest = ?

FORMULA:-

➛ Simple Interest = P×R×T/100

Where,

S.I = Simple Interest
P = Principal
R = Rate
T = Time

SOLVING BY APPLYING THE FORMULA:-

❖ Let the rate be R

↣ 600 = 10,000 × R × 3 / 100

↣ Cancelling the zeros.

↣ 600 = 100 × R × 3 / 1

↣ 600 = 300 × R / 1

↣ 600 × 1 = 300 × R

↣ 600 = 300 × R

↣ 600 / 300 = R

➛ 2 = R

Hence, we GOT the answer. The rate of interest is 2%.

TO CHECK:-

P = ₹10,000

R = 2%

T = 3 years

⇨ Simple Interest = P × R × T / 100

⇨ S.I = 10,000 × 2 × 3 / 100

⇨ S.I = 10,000 × 6 / 100

⇨ Cancelling the zeros

⇨ S.I = 100 × 6 / 1

⇨ S.I = 100 × 6

⇨ S.I = 600

Hence, checked. The S.I is Rs.600.

40.	Find domain and range of f(x) = x^2 + 10
Answer» Step-by-step explanation: Solution : f(x)= x-2 x-3 Domain of f(x) will be any real NUMBER except 3 as x=3 will make denominator 0. ∴ Domain =x∈R-{3}. To find range, we need to draw the GRAPH of f(x). Here, f′(x)= (3-x-x+2) (3-x)2 = 1 (3-x)2 ∴f′(x)>0. It means, graph of f(x) will always be increasing. Now, we can draw the graph of f(x). Please refer to the video to SEE the graph. From the graph, we can see that f(x) goes from -∞→∞ except -1. ∴ Range of f(x) will be (-∞,-1)∪(-1,∞).

Find domain and range of f(x) = x^2 + 10

Answer»

Step-by-step explanation:

Solution :

f(x)=

x-2

x-3

Domain of f(x) will be any real NUMBER except 3 as x=3 will make denominator 0.

∴ Domain =x∈R-{3}.

To find range, we need to draw the GRAPH of f(x).

Here, f′(x)=

(3-x-x+2)

(3-x)2

=

1

(3-x)2

∴f′(x)>0.

It means, graph of f(x) will always be increasing.

Now, we can draw the graph of f(x).

Please refer to the video to SEE the graph.

From the graph, we can see that f(x) goes from -∞→∞ except -1.

Answer»

Answer:

The correct answer is option (c).

Radhika bought a car =Rs.2,50,000.

Cost price of car =Rs.250000

Its price DECREASED next year =10%

Now, the price:

=250000−

×250000=Rs.225000

Next year, further its price decreased =12%

Now, the price:

=250000−225000×

100

12

=Rs.198000

Overall decreased percentage in two years,

=
