Question

Raj bought 15m red and 13 m black ribbon at Rs. 20 per meter. How much did he pay all? *​

Answer 1

Answer:

Step-by-step explanation:

Length of red ribbon = 15 m

Length of black ribbon = 13 m

Total length of ribbons = 15 + 13 = 28 m

Rate of ribbon = Rs 20/m

Therefore, total cost = 28 multiplied by 20

= Rs 560

Hence, Raj paid Rs 560 in all.

Answer 2

$\: \huge{\underline{\mathfrak\red{❥answer❣}}}$

➭ 15m red and 13m black ribbon

➭ Rs. 20 per meter

let's calculate the cost of one meter of ribbon ➭

15 = X × 20

X = 15/20

X = 0.75

➭ one meter of ribbon cost 0.75

let's calculate how much meter of ribbon did raj bought

15 = X - 13

X = 15 + 13

X = 28

➭ raj bought 28 meter of total ribbon

0.75 = X/28

X = 0.75 × 28

X = 21

Answer ➭ raj paid total 21 rupees to buy the ribbon
