Could anybody can teach me unitary method in arrow method​

Answer»

In simple terms, the unitary method is used to find the value of a single unit from a given multiple. For example, the price of 40 pens is Rs. 400, then how to find the value of one pen here. It can be done using the unitary method. Also, once we have found the value of a single unit, then we can calculate the value of the required units by multiplying the single value unit. This method is majorly used for ratio and proportion concept.What is Unitary Method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units. What can units and values be?Suppose you go to the market to purchase 6 APPLES. The shopkeeper tells you that he is selling 10 apples for Rs 100. In this case, the apples are the units, and the cost of the apples is the value. While solving a problem using the unitary method, it is important to recognize the units and values.For simplification, always write the things to be calculated on the right-hand side and things known on the LEFT-hand side. In the above problem, we know the amount of the number of apples and the value of the apples is unknown. It should be noted that the concept of ratio and proportion is used for problems related to this method.Example of Unitary MethodConsider another example; a car runs 150 km on 15 LITRES of fuel, how many kilometres will it run on 10 litres of fuel?In the above QUESTION, try and identify units (known) and values (unknown).Kilometre = Unknown (Right Hand Side)No of litres of fuel = Known (Left Hand Side)Now we will try and solve this problem.15 litres = 150 km1 litre = 150/15 = 10 km10 litres = 10 x 10 = 100 kmThe car will run 100 kilometres on 10 litres of fuel.

Rs 121 is the cost of 5kg of sugar, 5kg of wheat and 2kg of rice. The cost of 4kg rice, 2kg sugar and 5kg wheat is Rs 89. The cost of 3kg wheat, 2kg rice and 4kg sugar is Rs 95. Find the cost of each per kg by matrix method.​

Answer»

on:—RS 121 is the cost of 5kg of sugar, 5kg of wheat and 2kg of rice. The cost of 4kg rice, 2kg sugar and 5kg wheat is Rs 89. The cost of 3kg wheat, 2kg rice and 4kg sugar is Rs 95. Find the cost of each PER kg by matrix method. *Answer:—→ Sugar = Rs 40, → Wheat = Rs 18 and → Rice = Rs 25Step-by-step explanation:—→ Let the cost of 1 kg of sugar be Rs x→ Let the cost of 1 kg of wheat be Rs y→ Let the cost of 1 kg of rice be Rs z∴Cost of 5 kg sugar, 5 kg wheat, 2 kg rice = Rs 340 Cost of 2 kg sugar, 5 kg wheat, 4 kg rice = Rs 270 Cost of 4 kg sugar, 3 kg wheat, 2 kg rice = Rs 264Required system of linear equations:—5x + 5y + 2z = 3402x + 5y + 4z = 2704x + 3y + 2z = 264 ∴ AX = BPre multiplying by A⁻¹,X = A⁻¹B _______________(1)For matrix A,|A| = 5(10-12) -5(4-16) +2(6-20)or |A| = 22Thus, A is invertibleFinding COFACTORS of matrix A→ C₁₁ = -2, C₁₂ = 12, C₁₃ = -14→ C₂₁ = -4, C₂₂ = 2, C₂₃ = 5→ C₃₁ = 10, C₃₂ = -16, C₃₃ = 15∴Cofactor matrix of A :—Therefore,→ A⁻¹ = 1/ |A| ( adj A)or,Substituting in EQUATION 1,or,or,or,Thus, → x=40, → y=18, → z=25So, According to this we get:—Cost of 1 kg of sugar is Rs 40Cost of 1 kg of wheat is Rs 18Cost of 1 kg of rice is Rs 25

Rani jai and Seema receive a total of 2016 as monthly allowance from their mother such that Seema gets 1/2 of war Rani gets and jai gets 3/2 times Seema's share. How much money do the threesiblinger individually?​

Answer»

Total monthly allowance received by Huma, Hubna and Seem = ₹ 2,016 from their mother Seema GETS allowance = ½ of Huma’s share Hubna gets allowance = 1 2/3 of Seema’s share = 5/3 of Seema’s share = 5/3 of ½ of Huma’s share … [∵ given] = 5/3 × ½ of Huma’s share = 5/6 of Huma’s share So, Huma’s share + Hubna’s share + Seema’s share = ₹ 2,016 LET Huma’s share be 1, 1 + (5/6) Huma’s share + ½ Huma’s share = ₹ 2,016 (1 + (5/6) + ½) = ₹ 2,016 The LCM of the denominators 1, 6 and 2 is 6 (1/1) = [(1×6)/ (1×6)] = (6/6) (5/6) = [(5×1)/ (6×1)] = (5/6) (1/2) = [(1×3)/ (2×3)] = (3/6) Then, (6/6) + (5/6) + (3/6) = ₹ 2,016 (6 + 5 + 3)/ 6 = ₹ 2,016 (14/6) = ₹ 2,016 So, Huma’s share = ₹ 2,016 ÷ (14/6) = 2,016 × (6/14) = 144 × 6 ∴Huma’s Share is = ₹ 864 Seema’s share = ½ Huma’s share = ½ × 864 = ₹ 432 Hubna’s share = 5/6 of Huma’s share = 5/6 × 864 = 5 × 144 = ₹ 720Read more on Sarthaks.com - https://www.sarthaks.com/845980/huma-hubna-and-seema-received-total-016-monthly-allowance-from-their-mother-such-that-seemaStep-by-step explanation:it's not the exact ANSWER of your question but it may help you
