ratio between second and third part is 4: 3.​

Answer 1

Answer:

₹120, ₹300 & ₹225

Step-by-step explanation:

2/5 of second part :

\Large\frac{2}{5}

5

2

×\:4×4

\Large\frac{8}{5}

5

8

:\:4\::\:3:4:3

By taking LCM & cancelling with each ratio

New ratio = 8 : 20 : 15

Sum of the ratios = 8 + 20 + 15 = 43

1st part :

= \Large\frac{8}{43}

43

8

×\: 645×645

= \large\boxed{120}

120

2nd part :

= \Large\frac{20}{43}

43

20

×\:645×645

= \large\boxed{300}

300

3rd part :

= \Large\frac{15}{43}

43

15

×\:645×645

= \large\boxed{225}
