Answer
(1) Given:
Value of second property = ₹ 60,00,000
Ratio (Priya : Seema) =
Let us find L.C.M. of 5 and 7:
L.C.M. = 5 x 7 = 35
Priya : Seema =
Priya : Seema = 7 : 5
Total parts = 7 + 5 = 12
Value of 1 part = ₹ 60,00,000 ÷ 12 = ₹ 5,00,000
Priya's amount = 7 parts x ₹ 5,00,000 = ₹ 35,00,000
Hence, option 4 is the correct option.
(2) Given:
Value of first property = ₹ 38,00,000
Ratio (Priya : Seema) = 7 : 12
Total parts = 7 + 12 = 19
Value of 1 part = ₹ 38,00,000 ÷ 19 = ₹ 2,00,000
Seema's amount = 12 parts x ₹ 2,00,000 = ₹ 24,00,000
Hence, option 2 is the correct option.
(3)
Calculate total for Priya.
From 1st property:
Ratio (Priya : Seema) = 7 : 12 Given
Value of 1 part = ₹ 2,00,000 [From previous step]
∴ 7 x 2,00,000 = ₹ 14,00,000
From 2nd property:
Priya's amount = ₹ 35,00,000 [From step 1]
Total = ₹ 14,00,000 + ₹ 35,00,000 = ₹ 49,00,000
Calculate total for Seema.
From 1st property:
Seema's amount = ₹ 24,00,000 [From step 2]
From 2nd property:
Ratio (Priya : Seema) =
L.C.M. of 5 and 7 is 35.
Priya : Seema =
Priya : Seema = 7 : 5
Value of 1 part = ₹ 5,00,000
∴ 5 x ₹ 5,00,000 = ₹ 25,00,000
Total = ₹ 24,00,000 + ₹ 25,00,000 = ₹ 49,00,000
Difference = Priya - Seema
= ₹ 49,00,000 - ₹ 49,00,000 = ₹ 0
Hence, option 1 is the correct option.
(4)
Seema's 1st amount = ₹ 24,00,000 [From step 2]
Seema's 2nd amount = ₹ 25,00,000 [From previous step]
Ratio = 24,00,000 : 25,00,000
Ratio = 24 : 25
Hence, option 3 is the correct option.
