1st part
We have,
Worker W
1
=5
Weed a field in days=D
1
=12days
If,
Take worker W
2
=6
Then, Days D

=?
Then, we know that,
W

=10days
2nd Part,
If workerW

=15
Then,
Days D

=?
Then, we know that,
W

2)Answer: the interest on Rs 1700 at a 10 p.c.p.a. for 2 year is Rs 340
3)not know
4)in the given image
5)(-12)^7÷(-12)^7 = 1
Step-by-step explanation:

1. The given question is in indirect variation.
Hence, 5×12 should be equal to 6x
Hence x days,
- (5×12) / 6
- 10 days
2. Simple interest
= P×R×T
= 1700 × (10/100) × 2
= 1700 × (20/100)
= 17×20
= ₹ 340
3. (-10/11) ÷ (11/10)
= (-10/11) (10/11)
= -100/121
4. (13x³ - 12y² ) + (6x² - 8y²)
= 13x³ + (- 12y²- 8y²) + 6x²
= 13x³ - 20y² + 6x²
5. (-12)^7 ÷ (-12)^7
= (-12)^ 7-7
= (-12)^0
= 1 [Anything having power as 0, when computed, its result is 0.]
Hope it helps you, my friend !
