Given the ratio of the ages of two students = 5 : 3
Let their ages be 5<m:omath><m:r>x</m:r></m:omath> and 3<m:omath><m:r>x</m:r></m:omath>
After 6 years, their ages will be 5<m:omath><m:r>x</m:r></m:omath> + 6 and 3<m:omath><m:r>x</m:r></m:omath> + 6
Ratio of their ages after 6 years = 7 : 5
According to the question:
5<m:omath><m:r>x</m:r></m:omath> + 6 : 3<m:omath><m:r>x</m:r></m:omath> + 6 = 7 : 5
Product of mean = Product of extreme
⇒ 5(5<m:omath><m:r>x</m:r></m:omath> + 6) = 7 (3<m:omath><m:r>x</m:r></m:omath> + 6)
⇒ 25<m:omath><m:r>x</m:r></m:omath> + 30 = 21<m:omath><m:r>x</m:r></m:omath> + 42
⇒ 25<m:omath><m:r>x</m:r></m:omath> - 21<m:omath><m:r>x</m:r></m:omath> = 42 – 30
⇒ 4<m:omath><m:r>x</m:r></m:omath> = 8<m:omath><m:r>
⇒ x</m:r></m:omath> = 2
Hence the present ages of two students are 5(2) = 10 years and 3(2) = 6 years.

Let’s consider the number of 20 rupee notes to be x
And the number of 5 rupee notes be y

Then, according to the given conditions, we have

20x+5y=380     … (i) and

5x+20y=380−60

⇒5x+20y=320     … (ii)

Now, multiplying eq(i) by 4 and subtracting with eq(ii), we get

(80x+20y)−(5x+20y)=1520−320

⇒75x=1200

{tex}\begin{aligned} & \Rightarrow \mathrm{x}=\frac{1200}{75} \\ & \Rightarrow \mathrm{x}=16 \end{aligned}{/tex}

On substituting the value of x in eq(i), we get

20(16)+5y=380

⇒320+5y=380

⇒5y=380−320=60

{tex}\begin{aligned} & \Rightarrow y=\frac{60}{5} \\ & \Rightarrow y=12 \end{aligned}{/tex}

Therefore, 

The number of 20 rupee notes =16 and 

The number of 5 rupee notes =12

Given A circle with centre O and an external point T and two tangents TP and TQ to the circle, where P, Q are the points of contact.
To Prove: {tex}\angle{/tex}PTQ = 2{tex}\angle{/tex}OPQ
Proof: Let {tex}\angle{/tex}PTQ = {tex}\theta{/tex}
Since TP, TQ are tangents drawn from point T to the circle.
TP = TQ
{tex}\therefore{/tex} TPQ is an isoscles triangle
{tex}\therefore{/tex} {tex}\angle{/tex}TPQ = {tex}\angle{/tex}TQP = {tex}\frac12{/tex} (180o - {tex}\theta{/tex}) = 90o - {tex}\fracθ2{/tex}
Since, TP is a tangent to the circle at point of contact P
{tex}\therefore{/tex} {tex}\angle{/tex}OPT = 90o
{tex}\therefore{/tex} {tex}\angle{/tex}OPQ = {tex}\angle{/tex}OPT - {tex}\angle{/tex}TPQ = 90o - (90o{tex}\frac12{/tex} {tex}\theta{/tex}) = {tex}\fracθ2{/tex}= {tex}\frac12{/tex}{tex}\angle{/tex}PTQ
Thus, {tex}\angle{/tex}PTQ = 2{tex}\angle{/tex}OPQ

answer is 12 
double of 12 is 24 and 13+24=37

Let the number be x Then, 13+x=37 x=37-13 x=24
Let the number be x 13+(x+x)=37 x+x=37-13 x+x=24 24÷2=12 Therefore x=12

Rohit Yadav 3 years ago

Let the number be = x x+13=37 x=37-13 x=24 The number is 24 13+24=37

सूरदास के पदों कि काव्यगत विशेषताएं :-

 

1) सूरदास के पदों में भक्ति भाव

का वर्णन है। सूरदास भक्तिकाल के कवि थे ।

तथा भक्ति उनके काव्य में आना जायस था ।

सूरदास भक्तिकाल के सगुण भक्ति के कृष्ण

भक्त शाखा के अन्तर्गत आते है ।वस्तुत: उनके

कव्यो में श्री कृष्ण के प्रति प्रेम का वर्णन

दिखाई देता है।

उदाहरण :-

हमारे प्रभु औगुन चित न धरौ।

समदरसी है मान तुम्हारौ, सोई पार करौ।

 

2) सूरदास के पदों में वात्सल्य चित्रण देखने

को भी मिलता है । सूरदास ने कृष्ण के बाल

अवस्था का वर्णन करने हेतु वात्सल्य रस का

ही प्रयोग किया है ।

उदाहरण :-

जसोदा हरि पालनैं झुलावै।

हलरावै दुलरावै मल्हावै जोइ सोइ कछु गावै॥

मेरे लाल को आउ निंदरिया काहें न आनि सुवावै।

तू काहै नहिं बेगहिं आवै तोकौं कान्ह बुलावै॥

 

3) सूरदास ने अपने पदों में अलौकिक प्रेम की

व्यजना किया है । उन्होंने गोपी - कृष्ण के

स्वरूप अलौकिक प्रेम को दर्शाया है ।

 

4) सूरदास के पदों में ब्रज भाषा का पुट

मिलता है। उन्होंने अपने काव्य में ब्रज भाषा

का प्रयोग किया है साथ ही ग्रामीण, अरबी -

फारसी जैसे शब्दो को भी अपने काव्य में

स्थान दिया है ।

 

5) सूरदास ने अपने काव्यो में ' पद ' छंद का

प्रयोग किया है। उन्होंने ' पद ' छंद को महत्व

दिया है ।

 

सूरदास के संबंध में विद्वानों का विचार :-

 

आचार्य हजारी प्रसाद द्विवेदी के अनुसार -

 

" सूरदास जब अपने प्रिय विषय का वर्णन

शुरू करते हैं तो मानो अलंकार-शास्त्र हाथ

जोड़कर उनके पीछे-पीछे दौड़ा करता है।

उपमाओं की बाढ़ आ जाती है, रूपकों की

वर्षा होने लगती है। "

Step-by-step explanation:

37-[5+{28-(19-7)}]

=37-[5+{28-(12)}]

=37-[5+{28-12}]

=37-[5+{16}]

=37-[5+16]

=37-[21]

=37-21

=16

16
=37-[5+(28-{19-7})] =37-[5+(28-12)] =37-[5+16] =37-21 =16
