Transcript

Solution 6:

(i) 0.5 of Rs. 7.60 + 1.62 of Rs. 30

= 0.5\times7.60\ +\ 1.62\times30

= Rs. 3.80 + Rs. 48.60

= Rs. 52.40

(ii) 2.3 of 7.3kg + 0.9 of 0.48kg

=

2.3\times7.3\ kg\ +\ 0.9\ \times0.48\ kg

= 16.79 + 0.432

= 17.222

(iii) 6.25 of 8.4 - 4.7 of 3.24

= 6.25\times8.4\ -\ 4.7\times3.24

= = 52.500 - 15.228

= 37.272

(iv) 0.98 of 235 - 0.09 of 3.2

= 0.98\times235-0.09\times3.2

= 230.3 - 0.288

= 230.012
