Question

Can anyone know the answer of this question so please jaldi batao please

Answer 1

Answer: 1) total amount invented will ( 500 + 700) = 1200

2) simultaneously prlms, linear eqs

3) SI for 1st invent = 105 and SI for 2nd investment = 85

Step-by-step explanation:

let the 1st invent amount be x and 2nd amount be y then

ATQ, SI for 1st investment =( x*1*15)/ 100  as yearly said so one year will only be taken . next for SI for 2nd investment = ( y * 1 * 17 ) / 100.

In short SI for 1st inventsemt is 15x/ 100 and 2nd investment 17y/ 100

as said that total intest is 190 therefore

15x/100 + 17y/100 = 190 its first eq.

and now said that investment  amount is changed so now the 2nd eq will

15y / 100 + 17x/100 = 194 ( as said intrest will be increased by 4 more)

therefore . 17x/100 + 15y/100 = 194 is 2nd eq

now, solving the both the eq simultaneously

the we get x = 700 and y = 500.
