answer the maths question ​

Answer 1

Answer:

1. 15 kg : 210g

= 15000g : 210g

= 500:7

2. a) 65

b) 100

3. a) 5/4 * 100

= 5*25

= 125%

b) 0.02 = 2/100

2/100*100 = 2%

4. 20/100*2500

= 20*25

= 500 Rs

5. Let the quantity be x

40/100 x = 500

2/5 x = 500

x = 500*5 /2

x = 1250 km

6. Let her salary be x

10/100 x = 400

x = 4000 Rs

7. 1:4 = 1/4

percentage = 1/4 * 100 = 25%

8.

p = 1200 Rs

t = 3 years

r = 12%

Interest = ptr/100

= 1200*3*12 / 100

= 432 Rs

Amount = p + S.I.= 1200 + 432 = 1632 Rs

9. C.P. = 50

Profit = 12%

S.P. = ?

C.P. + Profit = S.P.

50 + 12/100*50 = S.P.

50 + 6 = S.P.

S.P. = 56 Rs

10. 50% of 164

= 50/100 * 164

= 82
