Kumar bought a transistor for Rs 960.He paid 12 1/2% cash money . The rest he agreed to pay in 12 equal monthly installment.How much will he pay each month.

Answer 1

At 1st the 12 1/2%of 960 = 960*25/2*1/100=120 rs.
so he payed 120rs of 960rs
now he have to pay 960-120=840
he wil pay each month=840/12=70 rs.

Answer 2

$\huge\red{ꫝꫀꪶꪶꪮ}$

Price of transistor = Rs.960

Amount paid in cash = 12.1/2% of  Rs. 960

= 25/(2 × 100) × 960

= Rs. 120

Balance amount = Rs 960 – Rs. 120

=  Rs. 840  

No. of instalments = 12

∴  Amount of each installment = Rs 840  ÷ 12

 = Rs. 70
