$(3:4)×2 and (2:3)×4 \\ </p><p> </p><p></p><p>=6:8 and 8:12 \\ </p><p></p><p></p><p>=6:8:12 \\ </p><p></p><p></p><p>∴6:8:12=3:4:6 \\ </p><p></p><p>$

Hence , the ratio of 3:4 & 2:3 is 3:4:6

The word percent means one part in every hundred.

Question 3

The ratio of 6h:8h is _________________

Solution 3

The ratio of 6h:8h is 6:8

Question 4

The compound ratio of 7:5 & 8:x = 84:60 then x = ______________

solution 4

The compound ratio of 7:5 & 8:x = 84:60 then x = 8

Question7

If Rs 5000 is invested in 8% per annum for 2 years at compound interest then amount will be _________

solution 7

Given: P=5000, R=8%,  T=2 years

Amount

$= p \times (1 + \frac{r}{100} ) {}^{t}$

$= 5000 \times (1 + \frac{8}{100} )$

$= 5000 \times (10.8) {}^{2} = 5832$

CI=Amount–Principle=5832–5000=832

∴  Amount is Rs.5832 and compound interest is Rs.832

Hence,If Rs 5000 is invested in 8% per annum for 2 years at compound interest then amount will be 5832

Question 8

The marked price of gift is Rs.176/- and sold it for Rs.165/- then discount percent is _____________

Solution 8

Given:

Marked price = 176/-

Selling price = 165/-

As discount is given on marked price so ,the discount is = Marked price - selling price

176-165.

Discount = 11/-

The discount percentage = (discount ×100/marked price)

= (11×100)/176

= 6.25%

Hence ,

The marked price of gift is Rs.176/- and sold it for Rs.165/- then discount is 6.25%

Question 9

The cost pair of shoes is 450/-. The sales of tax charged was 6%. The bill of amount is ________.

Solution 9

Cost of shoes =450, Tax =6%

BillAmount=Cost+Tax=C.P+6% of C.P

$= 450 + ( \frac{6}{100} ) \times 450 = 477$

∴ Bill amount is Rs.477

The cost pair of shoes is 450/-. The sales of tax charged was 6%. The bill of amount is 477/-

Question 10
