ANSWER:-

Q-1(3)



Q-2(4)




Let AB = 3, BC = 5 and AC = 4 unit

Then on applying Pythagoras in ADC = 16 = x
2 + AD2

in BAD = 9 = (5 – x)
2 + AD2

On subtracting = 7 = 10x + 25

10x = 32

x = 3.2

5 – x = 1.8

9/16 = 1.8/3.2 = BD/CD





माना की AB = 3, BC = 5 और AC = 4 इकाई

त्रिभुज ADC में पैथागोरस परिमेय लगाने पर = 16 = x
2+ AD2

BAD में = 9 = (5 – x)
2 + AD2

घटाने पर = 7 = 10x + 25

10x = 32

x = 3.2

5 – x = 1.8

9/16 = 1.8/3.2 = BD/CD

Q-3(3)


Q-4(4)


SI = 1000 × 12% × 4/12/100

SI = 40

A = P + SI

A = 1000 + 40 = 1040

Q-5(1)

Check from the options

500 × 3: 200 × 1: 100 × 3

= 15: 2: 3

विकल्प से जाँचिए

500 × 3: 200 × 1: 100 × 3

= 15: 2: 3

Q-6(1)

(a + b + c)2 = {a2 + b2 + c2 + 2(ab + bc + ca)}

400 = 152 + 2(ab + bc + ca)

124 = (ab + bc + ca)


Q-7(3)

(x3 + y3 + z3) =3/8 (x+y)(y+z)(x+x) 

Q-8(3)


Q-9(1)

Check through options

On putting 60
o we get the required answer.

विकल्पों के माध्यम से जाँच करें

60
o डालने पर हमें आवश्यक उत्तर मिलता है।

Q-10(3)

Let the marked price = 100

19% discount = 100 -19 = 81%

100% - 10% = 90%

90% - 90% × 4% = 86.4%

86.4% - 81% = 5.4%

5.4 × 100/86.4 = 6.25%


माना की अंकित मूल्य = 100

19% छूट = 100 -19 = 81%

100% - 10% = 90%

90% - 90% × 4% = 86.4%

86.4% - 81% = 5.4%

5.4 × 100/86.4 = 6.25%
